Seoul, Korea on Jan 03, 2007
Seoul, Korea - January 3, 2007 : Samsung Electronics Co., Ltd., the world leader in advanced semiconductor technology solutions, announced that it is now sampling its 16-gigabit (Gb) NAND flash memory with customers - the first NAND flash using 50 nanometer (nm) process technology.

The first samples of this high density NAND flash memory have a multi-level cell (MLC) design with a 4Kbyte (KB) page size to enhance both its read and write features. The new 4KB page function improves the conventional 2KB paging system for MLC NAND flash to double the read speed, while increasing write performance 150%.

By nearly doubling the overall performance of Samsung‘s MLC NAND, mobile consumers will enjoy faster data transfer speeds when storing or reading large data files whether they‘re using an external memory card, or a handset with a built-in flash solution such as Samsung‘s moviNAND?.

Early market introduction of 16Gb and higher density NAND flash memories is expected to accelerate the adoption of non-volatile memory applications such as flash-based solid state disks.

Samsung plans to begin mass producing its 16Gb NAND flash memory in the first quarter of 2007.
 

SAMSUNG Mass Producing Industry‘s First 1.8-inch, 64GB Solid State Drive, Targeted for Notebook PCs

Seoul, Korea on Jun 25, 2007
Seoul, Korea - June 25, 2007 : SAMSUNG Electronics Co., Ltd., the world leader in advanced semiconductor technology, announced that it has begun mass producing 1.8-inch solid state drives (SSD) at 64GB (gigabytes) - the highest density SSD available today for mobile computing applications.

"We see sharply increasing interest in SSDs among OEMs worldwide amid a growing push to launch premium SSD-based notebooks, particularly in the ultra-mobile category," said Jim Elliott, director, flash marketing, SAMSUNG Semiconductor, Inc.

SSDs feature far greater reliability, faster boot times and faster application start-up times than hard disk drives. SSD can also improve battery life by up to 20 percent in notebooks.

The 64GB SSD consists of 64 eight Gigabit (Gb) single-level cell flash memory chips. Use of 51nm process technology permits fabrication of much smaller components, with each chip having circuitry 1/2500th the width of a human hair.

SAMSUNG is aggressively expanding market development efforts for its SSDs. Industry wide attention on ultra-light, ultra-slim notebook PCs with flash memory based SSDs reflects early market support for this new storage medium. In addition, SAMSUNG has already introduced 32GB SSDs into ultra-mobile personal computers (UMPCs). SSDs also are being considered for server applications such as in advertising and for Web search engines. Other digital consumer products such as camcorders, PDAs and printers can now be equipped with SSDs ranging from 4GB to 64GB.

SAMSUNG‘s mass production of 64GB SSDs makes it the largest producer of high-capacity SSDs in the world.

Rapid expansion of the 1.8-inch SSD market will spark demand for even smaller SSD formats to be used in mobile consumer electronics. The miniaturization of SSDs will give rise to new types of digital products. Over the next three years, 2.5-inch and 3.5-inch SSDs will also gain a great deal of momentum for widespread use in standard notebooks and desktop PCs, respectively.

SAMSUNG expects that sales of SSD units will increase at a rapid 270 percent pace industry-wide between now and 2010 to become the largest growth segment in the NAND flash industry.
 

Samsung Introduces 1.8" - Type 64GB Flash-based Solid State Drive

on Mar 27, 2007 on Mar 27, 2007
Taipei, Taiwan - March 27, 2007 : Samsung Electronics Co., Ltd., the leader in advanced semiconductor technology, announced at its annual Mobile Solution Forum in Taipei that it has developed a 1.8”-type 64 Gigabyte (GB) flash-solid state drive (SSD). The new flash-SSD is based on an eight gigabit (Gb) single-level-cell (SLC) NAND, which provides significantly higher performance over conventional SSDs. The read and write performance of the new SLC flash-SSD have been increased by 20 percent and 60 percent respectively over the 32GB flash-SSD Samsung introduced last year, meaning that the new SSD‘s ability to outperform conventional rotating-media hard drives is even greater than had been anticipated. Samsung‘s continued nano-technology migration is a key enabling factor in the continued market segmentation for storage media. Besides the use of the 64 GB flash-SSD for notebook PCs, 8~16GB flash-SSDs will become viable solutions for use in personal navigation systems and digital camcorders, as will and hundred GB-level flash-SSDs for use in the server market. The flash-SSD, a drop-in replacement for a hard disk drive, is a secure and reliable means of storing personal or work-related data. It uses instantly-accessible, non-moving NAND flash memory instead of the noisier, power-hungry, jarring-sensitive rotating disc found in conventional hard drives, allowing it to upload and download data quickly and quietly with minimal power consumption. Samsung plans to start mass production of the 1.8"-type 64GB flash-SSD in the second quarter of this year. The SSD market is expected to reach US$200 million in 2007 and increases to US$6.8 billion by 2010 - an impressive compound annual growth rate of over 200 percent. 1.8"-type flash-SSD / rotating-disc HDD Feature Comparison Samsung‘s 64GB Flash-SSD Samsung‘s 32GB Flash-SSD 80GB HDD Read/Write Speed R : 64MB/s (4.3) W : 45MB/s (6.4) R : 53MB/s (3.5) W : 30MB/s (4.3) R : 15MB/s (1) W : 7MB/s (1) Weight 15g (1/4) 15g (1/4) 61g (1) Power Consumption O : 0.5W (1/3) I : 0.1W (1/15) O : 0.5W (1/3) I : 0.1W (1/15) O : 1.5 W (1) I : 1.5W (1) Note : 1.

Samsung Launches NAND Flash-based Solid State Disk for Mobile PCs

on Mar 21, 2006
Taipei, Taiwan - March 21, 2006 : Samsung Electronics Co., Ltd., the leader in advanced semiconductor technology, announced at the Mobile Solution Forum that it has begun offering a 32-Gigabyte (GB) NAND flash-based solid state disk (SSD) -- marking the first time that NAND flash has moved into mobile computing applications.

The 32GB Flash-SSD, which serves the same purpose as a hard disk drive, is a sophisticated data storage medium for notebooks and other mobile computers. It uses instantly-accessible, non-moving NAND flash memory instead of the rotating discs found in hard drives; therefore can upload and download data quickly and quietly with minimal power consumption.

The Flash-SSD weighs only half as much as a comparably-sized hard drive, but reads data three times faster and writes data 1.5 times faster. The SSD uses just five percent of the electricity needed to power a hard disc drive and is noiseless. Its design is free of any motor or other mechanical parts.

The commercialization of Samsung‘‘s 32GB Flash-SSD is a historic milestone for storage devices as it marks the initial entry of NAND flash memory in the mass mobile PC market.

Samsung sees the overall global SSD market surging from US$540 million in 2006 to US$4.5 billion by 2010.

Samsung Flash Solid State Drives (SSDs) Fully Compatible with Windows

on Oct 17, 2006
Seoul, Korea - October 17, 2006 : Samsung Electronics Co., Ltd., leader in advanced semiconductor technology, today announced that its three solid state disk (SSD) drives have been officially recognized by Microsoft Corporation as fully qualified Windows-compatible peripherals.

After thorough testing by its Windows Hardware Qualification Lab (WHQL), Microsoft has validated that Samsung SSDs meet all of the requirements for storage media in a Windows operating environment.

"Microsoft‘‘s certification of Samsung‘‘s SSDs provides designers with the added assurance of full compatibility in a demanding Windows environment, with our SSDs adding a strong dose of speed, reliability and power savings." said Jon Kang, senior vice president of Technical Marketing at Samsung Semiconductor.

Samsung‘‘s SSDs also markedly enhance system performance. The SSDs have a data read speed of 57MB/s and data write speed of 32MB/s, more than double the performance levels of a 1.8-inch HDD. Moreover, the SSDs provide a performance boost of up to 50 times that of a 1.8 HDD when servicing small, random data "read" requests. Such faster speeds shorten application program operating time as well as system boot time.

Samsung‘‘s new solid state memory solutions also enable longer battery life. Their power usage rate in an operational mode is less than 0.5W and in sleep mode just 40mW, which extends battery usage up to 30 minutes.

With no moving parts, Samsung‘‘s SSDs provide higher reliability with greater resistance against vibration, shock, extreme temperature, noise and heat emission.

Microsoft has certified a 32GB 1.8-inch sized Samsung SSD, a 32GB slim-type Samsung SSD (53.6x70.6x3.0mm) and a 16GB small-type SSD (56x48x3.8mm). The new sizes support the physical requirements of sub-notebook PCs.

The SSDs‘‘ substantial size and weight advantages are expected to further encourage a steady adoption of SSDs into a number of PC applications, such as in ultra mobile PCs, "ruggedized" notebooks and special industrial applications.

Seagate to industry: HDDs will continue to dominate storage

 

While NAND flash memory storage in the form of SSDs is being touted as the next killer application, manufacturers of HDDs (and some companies manufacture both) are not sitting in the park position. David Burks, director of product line management, consumer electronics, Seagate Technology, reminded the DISKCON 2007 audience that HDDs are still the storage technology of choice. He cited Gartner data showing that in 2006 <1.5% of all memory storage was in flash, but the forecast percentage only goes up to <5% by 2011 [see chart below].

The title of Burks‘ presentation, "Hard Drives and Flash Memory: The Virtuous Circle of Storage Technologies," drove home his main point. While much of the demand for flash memory storage is coming from consumer demand -- i.e., most content consumers want to retain on their personal devices (MP3 players, USB drives, digital cameras, etc.) -- this content is often originally stored on tethered PCs containing HDDs. And much of the content people want to download from Web sites is stored on enterprise servers or the server farms of sites such as Google, Yahoo, and YouTube, and these server farms are using HDDs for storage. Even content that is downloaded to flash memory devices, he noted, is often saved on backup systems that contain HDDs.

So as far as Seagate is concerned, the more flash memory devices that are sold, the greater will be the demand for HDDs, and HDDs will continue to dominate the storage industry. -- -- D.V. 

Samsung makes an enterprise play with SSDs

Date: ??, 2007

By Debra Vogler, Senior Technical Editor, Solid State Technology

The growing role that solid-state drives (SSDs), which use NAND flash memory to store digital data, are playing in the storage market was the subject of much discussion at last week‘s IDEMA DISKCON 2007 conference in Santa Clara, CA.

Jim Elliott, director of flash marketing at Samsung, was upbeat about the growing market for new applications using NAND flash memory, explaining that the NAND market is diversifying beyond consumer applications, such as USB drives, MP3 players, and the cell phone, to SSDs. He noted that the cost of NAND flash is decreasing ~50%/GB/year, while density is increasing at a rate of 2X/yr. The typical density range for an MP3 player as well as cell phones is ~512MB?8GB; for SSDs, the range is 32GB?64GB.

Samsung expects several additional key growth areas for NAND flash: DSC/DSLR, DVC, and car navigation/GPS systems. Presenting market data from the SEC, Elliott anticipates a >14X GB increase between 2007 and 2010 for the navigation market, with the number of units surging from slightly less than 30M in 2006 (portable and built-in units combined) to >100M units by 2010.

As NAND storage densities continue to increase, Samsung sees a major opportunity in the notebook space -- projecting that 71% of capacity requirements in corporate notebooks are <60GB, according to Elliott. But the "play" is not just in the market itself ? rather, a chance to get past the seasonal cyclicality (i.e., year-end holidays) imposed by the proliferation of applications in consumer electronics at the lower density levels. Because SSD densities have now reached the level required for corporate notebooks (64GB), Samsung believes the time is ripe to pick this low-hanging fruit.

Key to selling into corporate IT customers, Samsung believes, will be SSD attributes of reliability, high-impact resistance, light weight, and overall performance (e.g., sequential read/write speeds) and low power consumption. However, there‘s evidence that the pitch is working for more than just the corporate notebook customer -- the company recently announced that its 2.5" SATA 64GB SSDs are available in Dell and Alienware consumer notebooks. Dell is offering Samsung‘s SSD drive on its XPS M1330 ultra-portable notebook, with plans to make it available across additional XPS systems and its Latitude corporate notebooks and Precision mobile workstations later this year. Alienware is going to provide a 128GB SSD configuration, using dual 64GB SSD drives in a RAID 0 array, in addition to a single 64GB SSD combined with a large capacity 200GB 7200RPM drive for the Area-51 m9750 gaming notebook.

The next adjacent market Samsung is targeting is the sophisticated gamers -- but these gamers aren‘t "kids," Elliott noted, pointing out that the average gamer is 31 years old and typically buys 2-3 PCs a year to take advantage of newer faster processors or memory types. "These are people very in tune with performance, so an SSD is another arrow in the quiver to have the fastest PC on the block," he said. The size of the gaming market segment belies the fact that this demographic is at the leading edge of the technology adoption curve, Elliott added. "The gamers are the thought leaders, these are the guys who blog [and] post performance metrics; they see which way the industry is going."

Once SSD densities get above 100GB, Samsung‘s next target market is the mass consumer, for which it plans to offer 128GB SSD densities by the end of 2008. After that, the company expects SSD densities to continue to increase, but it is also researching the possibility of combining single- and multi-level cell (SLC and MLC) technology to drive down cost and get further leverage in the consumer electronics space. SSDs currently use only SLC technology for higher performance and better endurance, Elliott explained, but because MLC has a much smaller die size/GB it‘s possible to get anywhere from 70%-90% more GB/wafer (depending on lithography and yields) ? and even with MLC‘s lower yield, it is an attractive proposition for driving down cost in consumer electronics storage devices.

Although work is still in the R&D stage, the company hopes to be the first to offer the SLC-MLC combination. "We‘re very well positioned," Elliott told WaferNEWS. "We have ~90% market share on SLC flash, so we expect to leverage off our SLC portfolio, and we‘re the world‘s largest MLC supplier as well." -- D.V.
 
 

Samsung Introduces Server-Grade NAND flash for SSDs

Samsung Electronics announced today that it collaborated with Sun Microsystems to develop a SLC NAND flash memory with five times the endurance of conventional NAND flash memory. This would put the "ultra-endurance server-grade" flash memory at 500k program/erase cycles.

To extend the endurance, Samsung likely tweaked the underlying cell process and/or modified the programming algorithm. The net result is that the improved endurance comes at the expense of reduced performance or retention. However, by targeting high transactional enterprise applications with this device, the degraded retention should not be an issue.
 

Toshiba Eyes 50% Share of Notebook SSD Market in 2010

May 9, 2008 19:52
Shinichi Kato, Nikkei Microdevices

Atsutoshi Nishida, president and CEO of Toshiba Corp, expressed the company‘s commitment to solid state drive (SSD) with multi-level NAND flash memory at the corporate strategy meeting for fiscal 2008 in Tokyo on May 8, 2008.

"We aim to win at least a 50% market share for SSDs used in notebook PCs in 2010 or 2011," Nishida said.

The company expects that SSD-equipped machines account for 10% of all notebook computers in 2010, and 25% in 2011.

For the development of SSD technology, Toshiba organized a company-wide project team, feeling that it would be too difficult for Toshiba Semiconductor Co to be able to handle the multi-level NAND flash memory by itself. Members of the project were brought together not only from Toshiba Semiconductor but also from Toshiba‘s personal computer and HDD departments, in addition to the heads of R&D for the entire company.

"I asked the related sections of the HDD business that might compete against SSD technology for their support and gained it," Nishida said. "I told them that unless they provided their expertise and complete cooperation, the company would not make any further investment in HDD technology."

Nishida emphasized that not many competitors can keep up with Toshiba in the development of multi-level NAND flash memory because it is an extremely difficult technology. This is why Toshiba aims to win at least a 50% market share for SSD used in notebook PCs, he said.

固态存储盘(SSD)的发展之快将超出预料

 
 硬盘(HDD)不仅在个人消费电子设备领域基本被NAND闪存/卡挤兑得几乎无容身之地,如今,在它占据主导的PC/服务器数据存储领域,也开始受到后者的巨大威胁。NAND闪存在功耗、速度、数据可靠性、重量以及静音等方面具有非常明显的优势,随着轻薄型笔记本电脑在整个PC市场份额的持续增加,NAND的这些优势变得更加具有吸引力,基于NAND闪存的固态存储盘(SSD)正在逐步走入这些应用。

“由于价格还太昂贵(上千美元),目前我们的SSD主要面向出口,国外一些个人笔记本用户和服务器用户对此有一定需求。虽然短时间内容它还不可能取代已达T级容量的硬盘,但发展势头不错,市场前景很好。”本土SSD制造商忆正存储技术(深圳)有限公司资深工程师黄河指出。

的确,SSD正不断朝更高容量密度/耐用性和更低价格演进,促使它在整个存储器市场的份额逐年增加。如图1所示,Gartner预计2012年将发展成44亿美元的市场规模(有人称这一预测过于保守,实际发展速度将更快),而这一切得益于NAND闪存技术的进步以及巨头公司们的推动。


图1:未来几年SSD与HDD设备的市场预测(来源:Gartner)。

<>< b=""> <>

很多读者一定已经了解到,就在6月初,当存储器巨头三星公司刚刚宣布推出42nm闪存芯片不久,英特尔与美光就宣布其闪存合资公司IM Flash Technologies已开发出34纳米的32Gb的多层单元(MLC)和16Gb单层单元(SLC)芯片,使得每GB的成本价降低到1美元以下,将三星、东芝、Hynix等其他巨头抛在身后(领先半年左右,见图2)。


图2:NAND闪存巨头之间工艺竞赛曲线。

英特尔在工艺技术方面领先性常常让人“叹为观止”,如今在闪存工艺开发上得到了充分发挥。美光存储器系统开发部副总裁Dean Klein不久前在世界巡回发布会上展示了一个用于新一代34纳米器件生产的300毫米晶圆(图3),指出其上可切割出400个左右的32Gb芯片,相当于每片晶圆包“产出”1.6TB的NAND闪存容量。而IM Flash Technologies已在研发20nm工艺级别的64Gb MCL闪存器件,预计将于2009年问市,不过Klein没透露具体细节。


图3:用于新一代34纳米NAND器件生产的300毫米晶圆,可切割出400个左右的32Gb芯片。

不仅在工艺上有重大突破,此新器件也标志着标准NAND向高速NAND的转变,其读写的速度有5-6倍的提升,极大地提高了存储器带宽,特别适用于SSD、USB3.0、超高速缓存盘、视频点播服务器、混合硬盘驱动器等应用,而对于其他一些关键特性亦有显著改进(如表1),另外,器件接口标准支持实现了从ONFI1.0向ONFI2.0的转变(备注:ONFI是Open NAND Flash Interface的缩写,它是由英特尔发起的一个标准联盟,旨在统一行业中所有NAND器件、NAND模组、主机控制器以及驱动软件之间的接口,不过东芝和三星并不买帐,没有加入该联盟,而是另起炉灶,共同制造基于东芝开发的另一种接口标准LBA的NAND闪存产品,也得到了不少下游厂商的支持。)


表1:标准NAND与高速NAND的一些关键特性对比。

芯片供应商积极介入SSD成品供应

美光NAND市场开发总监Kevin Kilbuck透露,他们共有三个300毫米晶圆厂,位于美国Viegina州的工厂已达到100%产能,位于Utah州的另一个工厂在未来几个月也将达到100%产能,而在新加坡新建的工厂将在本月竣工,2009年会增加产能。据悉,英特尔与美光将平分以上所有产能,但各自独立进行产品推广和销售。两大公司的强势进攻无疑将在NAND应用市场有所斩获,对此其他巨头决不可能坐视不管,业内人士都认为,更加激烈的技术和产能竞赛将会在下半年上演。

被视为NAND新机遇的SSD市场自然也会被波及,不过这种影响是积极的,因为将加速SSD价格的下降,推动它的普及。业内普遍预计SSD价格每年下降速度为40-45%。而另一个催化剂就是,除了提供新一代高速闪存芯片给SSD制造商,数得上名的NAND闪存芯片巨头们都在推出自己的SSD产品。以美光为例,目前他们面向笔记本和台式PC市场的1.8和2.5英寸SATA接口SSD产品C200最高容量已达到256GB(基于34纳米闪存器件),基于MLC NAND,连续读取速度为200MB/s,连续写速度为120MB/s。面向对性能要求更高的服务器、工业和网络应用设备市场,美光也推出了基于SLC NAND的2.5英寸SATA SSD产品 P200,连续读取速度达到250MB/s,连续写速度达到250MB/s。据Kilbuck介绍,SLC型产品的耐用年限为10年,MLC型产品能达到5年左右,当然这与主控制器的配合使用也有很大关系。


图5:美光的NAND产品组合简图(注:控制器是搭配其它公司的产品)。

美光没有透露他们采用了哪家公司的主控制器,有业内人士猜测,可能是采用了英特尔的嵌入式控制器,专门针对SSD应用进行了优化,可以节省SATA桥芯片。忆正存储技术(深圳)有限公司资深工程师黄河则表示,为满足设计需要,他们也使用了自己设计的主控制器。

笔者认为,存储器芯片厂商介入SSD成品的供应将会对纯粹的SSD制造商产生一定冲击,不过由于该市场方兴未艾,对每个人来说机会将大于挑战。

满足日益增长“户外”存储需求,英特尔将为超级便携式PC提供嵌入固态硬盘

英特尔公司即将为其超级便携式PC平台嵌入SSD(固态硬盘),旨在满足用户日益增长的“户外”存储需求。Z-P140 PATA固态硬盘将作为一种可选式模块向OEM厂商供给,供它们嵌入在面向Menlow平台的主板上。

Menlow平台面向超级便携式PC,它还包括Silverthorne处理器和Poulsbo芯片组。据英特尔公司的产品经理拉尔森在上周五招开的一次会议上表示,基于Menlow平台的产品将在2008年的上半年上市销售。

这种微型SSD芯片只有0.6克的重量,其容量分别为2GB和4GB。据拉尔森表示,通过将四个这样的SSD芯片连接到一个标准的PATA接口,主板上的存储容量可以扩展到16GB。然而,由于没有机械部件,SSD的能耗低于传统硬盘,因此,它们更适用于便携式设备中。据英特尔公司的营销经理特洛伊表示,Z-P140 PATA的存储容量在两年后将达到64GB。

除此之外,英特尔公司还表示,它计划在明年1月份举行的消费电子产品展会(CES)上展示由华硕、明基、联想等厂商生产的基于Menlow平台的超级便携PC。并于2009年推出Moorestown━━新的超级便携式PC平台。

 
 
 

固态硬盘市场爆发,Jedec将制定行业标准

 主要为DRAM接口制定标准的Jedec组织最近新成立了一个标准小组,为采用NAND闪存芯片的固态硬盘制定标准。JC-64.8委员会将制定用于嵌入式或可移动存储设备的固态硬盘标准,以推动现有存储设备的发展。

该标准小组由Seagate公司的Alvin Cox和Micron的Scott Graham联合担任主席,于5月份举行了首次会议。在2007年8月召开探讨会和对业内公司进行一次调查之后,Jedec联盟决定成立这个标准小组。

据Jedec最近发表声明,委员会将定义“接口标准中所没有包含的推动现有接口标准(命令协议和电气接口)的新参数、机械互连、工作环境、电气特性、可靠性测试方法和操作步骤。这个新的标准小组旨在和相关的Jedec委员会以及其它定义大容量存储标准的协会(包括串行ATA国际组织,USB3.0协会和其它组织)协同工作。

与此同时,另有两个由Intel主导的小组正在着手开发用于满足闪存硬盘要求的闪存芯片和闪存控制器接口标准。非易失性存储主机控制器接口工作组(NVMHCI)于2008年4月宣布此计划,而开放NAND闪存接口小组(ONFI)早在2006年5月就有此计划。

Jedec组织目前仍在吸收会员。Jedec董事会主席Mian Quddus在一份声明中表示,“业界需要集思广益来制定固态硬盘标准,用于使全球市场尽快接受具有最佳性能的SSD产品,使消费者的利益最大化。”

此前不久,Samsung和Sun Microsystems发表了一份联合声明称已合作开发一项针对计算机服务器用闪存驱动的8G单层单元(SLC)新设计。据这两家公司称,他们将NAND闪存芯片的读/写周期提高了五倍。另外,新兴公司Fusion IO和惠普目前正合作开发闪存控制器。

据International Data Corp预测,到2012年固态硬盘产量将达到2.2百万,市场销售额将达到900,000,000美元。目前固态硬盘的市场销售额为260,000,000美元。

  1. 来自IDC、iSupply 和Trendfocus 等机构的统计数据表明,06 年全球硬盘出货量在4.3 亿个左右,同比增长12.9%,2010 年前仍可保持10%以上的CAGR。我们根据多方数据,自己模拟的预测结果(如上)也大致相同。因此我们仍对未来几年内硬盘市场持较为乐观态度。
  2. 而从上图我们可看出,硬盘的增长主要来自于笔记本电脑和消费电子产品的快速增长。而对于各类产品增长的动力,我们推测如下:
    1. 台式机:1)Vista 07 年的推出,将刺激消费者提高硬件配置而加快更新速度;2)亚洲、非洲的市场空间还较大,在中国“电脑走进农村”07 年起力度也明显加大。
    2. 笔记本:替代台式机速度不减,且价格下降进一步扩大了潜在消费群体。
    3. 消费电子:配备1”以下微硬盘的手机、DV、PDA 等开始进入快速上升通道,DVR、机顶盒、视频监控的流行则拉动了3.5”大硬盘的快速增长。虽然我们预计09 年后,移动便携设备中的1”以下微硬盘将逐渐被SSD(固态硬盘)替代,但整体消费电子硬盘快速增长仍将保持一段时间。
    4. 企业应用:在全球向以视频、图片等为代表的数字媒体2.0 时代过渡中,海量数据存储、灾备以及高速检索成为普遍现象(我们可看到Youtube 这样的视频网站越来越多),因此我们保守估计,未来也可保持5%-7%的稳定增长。
硬盘下游各产品未来增长动力如下。
1、台式机:Vista + 亚非空间还很大
2、笔记本:替代台式机增速不减
3、消费电子:便携式设备和DRV、机顶盒等媒体设备正处于快速上升通道
4、企业应用:向数字媒体2.0 时代的过渡导致对视频、图片等数据存储需求的大增

SSD(固态硬盘)短期难撼硬盘主流地位

  1. 我们的观点是:4年内我们的观点是:4 年内 SSD 难撼硬盘主流地位。主要是SSD 价格短期内还无法被大多数消费者接受。业内主流观点是1)到2010 年,32GB 以下的微硬盘可能会被SSD 取代;2)硬盘和SSD 会共存相当长的时间:硬盘向大容量数据存储方向发展,SSD 主要用在移动便携式设备中。
  2. Dell、Samsung、Sony 都在今年推出了SSD 笔记本,其中Sony 在07 年8 月发布了一款配备32GB SSD 的笔记本,售价2099 美元,所附带的32GB SSD 价格在480 美元左右。目前主流笔记本硬盘都在80GB 以上,我们用下图预测了配备64GB SSD 笔记本未来的价格走势(考虑到届时厂家可能因SSD 价格贵而缩小了容量,以降低整个笔记本的价格)。假设其他部件价格不变。

企业盈利能力有望改善,装配环节外包继续扩大

价格战不再激烈,企业盈利能力有望改善

  1. 最近全球排名前两位的硬盘厂商Seagate 和WD 纷纷调高了08 财年Q1 的盈利预测,其中一个主要原因是认为未来价格战压力减小,看好硬盘价

格下降速度趋缓。

  1. 随着近几年的并购和重组,全球硬盘企业数量迅速减少,目前Top5 已经占据90%以上市场份额。未来,在较为稳定的竞争格局下,我们认为企业战略将从争夺市场份额变为注重盈利能力,历时数年的硬盘价格战带给企业的压力将有所缓解

因价格战压力减小,硬盘巨头纷纷调高08FYQ1的盈利预测。

来源:iSuppli、TFI

外包比例继续加大

  1. 全球电子制造业外包比重不断扩大已是众所周知。根据TFI 统计,2005 年全球总外包量超过2000 亿美元,EMS/ODM 渗透率约为19%,预计2010 HSA 业务外包因素在于:年增长到25%,外包总量超过4000 亿美元。
  2. 我们看好硬盘制造外包细分领域的未来增长。从硬盘产业链来看,我们认为利润率最低的HSA(磁头堆装配)业务,是未来外包发展最快的环节。就出货量而言,目前硬盘厂商56.2%的HSA 业务自产,43.8%的业务外包给TDK、长城开发和ALPS。而今年3 月,ALPS 已与TDK 签订协议将磁头业务卖给TDK。之后独立厂商就仅TDK 和长城开发两家。我们预计HSA 外包比例将在2011 年达到56.8%(根据最新预测,与前期报告比我们稍作调整,下同)。进一步我们认为,在HSA 独立厂商市场份额不断提高的趋势下,HSA 企业相对硬盘厂商的议价能力也将逐渐提高。

HAS业务外包因素在于:
1)降低成本,并将资源投入到较高利润的硬盘其他环节中。
2)建立后备生产线,降低仅自身单一生产的风险。

 

 

 

 

 

 

 

硬盘产业链(横向是工序) 全球HAS竞争格局

受下游硬盘厂商价格压力减轻、HSA 外包比例加大提升定价权的影响,我们认为未来HSA 企业来自下游的压价情况将可能好转,自身盈利能力存在提升的可能。

News Analysis




Event

On 14 January 2008, EMC announced it will integrate flash-based solid state drives (SSDs) into its core product portfolio, the EMC Symmetrix DMX-4 storage system. Preliminary performance claims for the DMX flash drives are a tenfold improvement in response times and a thirtyfold improvement in maximum input/output rates relative to physical disk drives of equivalent capacity. EMC plans to offer flash drives in 73GB and 146GB capacities later in 1Q08. Prices were not released.




Analysis

SSDs deliver order-of-magnitude performance improvements, enhanced reliability and lower power consumption than contemporary physical disk drives. SSDs do this by eliminating the mechanical delays associated with traditional spinning disks; delivering more bandwidth and mitigating write penalties by leveraging algorithms that optimize parallel activity.

The two primary barriers to broad market acceptance of SSDs are cost and the ongoing performance improvements of RAID storage systems. Whether DMX flash drives — nominally priced at 30 times the cost of a physical disk of equivalent capacity — will surmount these barriers to become a market success remains uncertain. Flash drives are the first SSD option offered in a general-purpose, high-end storage system, but the modest success of earlier SSD systems and drive options suggests that flash drives may be a niche product. Balanced against this concern is the possibility that the lower cost of flash drives in absolute dollars, on a dollar-per-GB basis, may allow them to become a mainstream success.

The use of nonvolatile flash memory instead of dynamic random access memory (DRAM) eliminates the need for battery backup but raises concern about flash drive service lives. The flash drive design addresses this concern by using enterprise-class single-level cell (SLC) NAND flash components and advanced flash management techniques in the drive, resulting in longer mean times between failures (MTBFs) and improved mean times between data loss (MTBDLs) than RAID sets built using physical disks.






Recommendations



  • Users with applications bottlenecking on performance: Consider installing flash drives where performance needs and capacity requirements make them an optimal solution.
  • All users: Require availability guarantees that are easily enforceable and include meaningful remedies until the market validates DMX flash drive technology.
 
 
 

SSD取代硬盘的模式


东芝半导体社长斋藤升三演讲中提到:2011年将会有1/4的笔记本电脑内建SSD。到底SSD有什么魔力,取代传统的硬盘,又SSD会以什么样的姿态来取代硬盘呢


传统式硬盘一向是计算机里一个为人诟病的零件,撇开机械式老旧且不耐震之外,它的重量就足以让笔记本电脑的整体重量压不下来,其他像是发出噪音、寿命短、数据传输速度慢等一连串的缺点,不禁让人问:这是电子时代该出现的产物吗?

我们一直在找寻取代硬盘的大容量储存装置,但都寻寻觅觅,直到半导体制程的突破,连带拉起的NAND FLASH储存技术崛起。NAND Flash具备有电子式的储存,完全没有任何一个机械装置,重量可以压到硬盘的好几十分之一,传输速度比硬盘来的快,耐震且体积小,在任何一点来看都是优于硬盘,唯其存取寿命有限,但在SLC(Single-Level-Cell)方面却还是大有可为,十万次的存取次数以及比MLC(Multi-Level-Cell)快上三倍的速度,皆是取代硬盘的不二人选,足够用于操作系统碟7年到10年以上。

混合硬盘:传统硬盘 + SSD
目前,SSD受制于单价仍远高于传统式硬盘,短期间很难能100%取代硬盘。但基于对SSD的需求,所以出现了混合硬盘的形式。混合硬盘即一个SSD碟当作是操作系统碟,计算机的操作系统安装在此碟中,在开机关机、存取数据或是耐震上,皆有不错的表现,而大量的数据则储存在传统的硬盘上,由于传统硬盘有CP值上的优势,故可以做大容量的数据保存。另外,一般数据存取并不影响到震动中操作系统的正常运作,因为作业统是放在SSD碟里面的。这样的组合同时可达到极佳的效能,也达到降低成本。依照现在市面的价钱来看,16G SLC SSD搭配160G/250G的传统硬盘是比较划算的组合。

混合硬盘:SLC SSD + MLC SSD
前面提到SLC制程的SSD会比MLC SSD价钱来的高,原因在于SLC的制程难度较高,但其one-by-one bit传输的特性,让他的传输速率比MLC制程的NAND FLASH快上三倍,寿命是MLC制程的10倍,而耗电量又略小于MLC制程的优势(SLC NAND FLASH约略减少15%的耗能),让SLC SSD成为追求快速与稳定的操作系统槽的不二首选。但是在非系统程序数据存取方面,由于数据极少搬动且不追求高速的情况下,可以采用单价较低的MLC制程的SSD当作数据存放的区域。目前市面上畅销的ASUS Eee PC即是采用此一策略,缺点是MLC制程的SSD价钱仍旧高于一般的传统硬盘。

SSD应用范围
目前SLC SSD的大容量储存方案,主要用于航天或是军事用途,作为高速用途的装置上面,单价虽高但具备速度快寿命又长且耐震的特性,适用于航天工业或是军事用途等比较在意效能且环境较恶劣的情况下使用。而小容量的SLC SSD储存方案,目前主要应用在笔记本电脑的系统磁盘上,由于小容量SLC SSD单价比高容量的低,但容量足以应付系统磁盘的需求。

MLC制程的储存方案应用范围就比较广了。举凡市面上目前大多数的NAND FLASH的应用如MP3、随身碟、手机、照相机、记忆卡或是其他小零件的应用,几乎都是以MLC NAND FLASH为主,原因无他,就是因为MLC的价钱低,而这些装置的运作是不需要高速的需求的。但是MLC的寿命也是一大障碍,尤其是对于随身碟这一类型的装置,常需要放置重要文件,所以风险不小。

而混合型的硬盘应用范围大多用于笔记本电脑及追求效能的桌面计算机。因为笔记本电脑对于耐震的要求十分贴近SSD的需求,再考虑价格的因素下,SSD加上传统硬盘或是SLC SSDMLC SSD是一个很好的解决方案;而在计算机的应用方面,可以参考笔记本电脑的方案或是另一个由Intel提出的概念-Turbo MemoryTurbo Memory即在计算机主机里面加装一个小容量的SSD,在关机的时候将RAM里面所执行的数据加载到SSD里面,下次开机的时候直接将SSD里面的信息加载RAM里面,节省了许多开关机的时间。

结论
对于SSD的最大的关键还是在于价钱,但人类目前追求半导体制程的演进以及其他算法的改良,SSD取代硬盘势必是未来的趋势了,就看看市场如何反应或是有什么新的应用推出。

惠普在服务器市场出货量与营收都成为第一名


根据研究机构Gartner调查显示,2008年第一季全球服务器出货量为227万台,比起2007年第一季211万台,年成长率达7.6%。市值达136亿美元,比起去年同期130亿美元,年成长率为4.3%


惠普不仅在PC市场成为龙头,在服务器市场也成为龙头。根据Gartner研究显示,2008年第一季惠普的服务器出货量达68.3万台,年成长率为7.6%。更重要是惠普在服务器营收上的年成长率达10.3%,高于出货量成长率。 可见得其开始往IBM长期主导的高阶服务器市场前进。

2007
年时惠普在服务器营收上仍旧落后于IBM,进入2008年,由于惠普ProLiantIntegrity系列的服务器热销,使得惠普第一季服务器营收达到40亿美元,超越IBM39亿美元,市场占有率也向上增加了1.6个百分点,达到29.6%。此外,惠普在Blade服务器市场的营收也比去年同期成长13%以上。

在营收成长率上,第二名的IBM,第三名的戴尔,第五名富士通/富士通西门子,年成长率分别为2.1%6.6%4.9%。只有第四名的升阳,呈现负成长的情况。

惠普在2008年第一季服务器出货量比去年同期成长7.8%,在全球服务器市场占有率上突破30%,达到30.1%

戴尔仍是全球第二大服务器出货量厂商,2008年第一季出货量达到51.6万台,比起2007年第一季的44.6万台,年成长率达15.8%,是前五大厂商中成长率最高的厂商,市场占有率也提高至22.7%

从出货量来看,IBM和升阳的服务器年成长率分别为2.3%6.6%。至于第五名的富士通/富士通西门子出货量成长率却呈现下滑2.6%。(719字)

2008年第二季PC出货量成长率超乎预期


根据研究机构IDCGartner研究显示,2008年第二季全球PC出货量成长率都超出预期的好,分别为15.3%16.0%。主要原因是新兴市场需求强劲,以及欧美PC市场以降价刺激需求,年成长率不仅高于第一季,且季成长率也都是正数,呈现淡季不淡的情景。


Gartner原本预估第二季PC成长率只有11.2%,可是根据其统计发现,成长率竟然高达16%,令人吃惊。IDC也是得到相同的结论。

IDC
认为第二季PC出货量会如此亮丽,主要原因包括:产品更新、在通路上厂商之间竞争加剧与平均销售价格下滑所致。基本上来说,消费者面对财务压力还能够产生如此稳定的成长率,可见得PC在生活上的角色愈来愈重要。原本Gartner预期美国PC市场出货会衰退近2%,但实际上却成长4.2%

在厂商表现方面,惠普除了在美国市场仍输于戴尔之外,其他市场都位居第一名宝座。根据IDC研究,惠普以18.9%全球市场占有率居于领先地位。在美国却与第一名的戴尔差距又拉大。

+
者之间市场占有率差距为6.6%,比起第一季差距6.4%,以及去年同期差距4.8%,又开始逐渐拉大两者之间差距。IDC认为戴尔在通路策略,尤其是扩充零售方式已经生效。

无论GartnerIDC都认为,如果美国经济情况若因为油价与次级房贷又变的更糟,则年底惠普与戴尔之间的价格战又在所难免。

第三名仍是宏碁的天下。不过,根据Gartner数据显示,苹果2007年第二季在美国麦金塔销售量攀高至139.7万台,比起宏碁/捷威的133.1万台,高了0.4%的市场占有率,因此宏碁何时整合捷威资源,并达到综效是其保卫美国第三名宝座的关键点。(860字)

华硕Eee PC推出第二代,挑战更多


2008年的Cebit展,一共有来自7个厂商展示8款低价迷你笔记本电脑,主要原因当然是华硕于2007年成功推出7Eee PC有关。此次,华硕也顺势推出下一代Eee PC,尺寸为8.9吋。


为了达到2008年出货量500万台的目标,华硕于2008年的Cebit展示了第二代Eee PC

第二代Eee PC同样是采用900MHz英特尔Celeron M处理器,屏幕尺寸为8.9吋,分辨率为1024 x 600。此外,华硕加大其固态硬盘至12GB,以及RAM1GB起跳。目前在未安装Windows XP的情况下,预估售价为399欧元(约606美元)。如果安装之后,将会高于此价格!

华硕认为,在已开发国家中,年轻人、家庭主妇与年纪较大的人将成为第二代Eee PC的目标市场。

在第一代Eee PC时,无论是开发中国家或者是已开发国家,都因为内建Linux操作系统的Eee PC,而造成风潮。例如美国亚马逊还曾经几周Eee PC系统产品销售量排行在前十名之中,占据了5个名额。

当然Eee PC也激起了许多开发中国家的PC厂商起而效尤。例如:印度的HCL厂商,就在2008年初,推出350美元且7吋屏幕的迷你PC,甚至在情人节时推出粉红色版本。

同样的本次Cebit展,有许多厂商加入展示的行列,包含Packard Bell(已被宏碁买下)MedionGecube(精星科技)、ElonexE-Lead(怡利电子)、Clevo(蓝天计算机)与Amoi(夏新电子)。

其中,Packard Bell将在欧洲推出Dixon7吋迷你便携计算机。其是采用1.2GHz威盛的C7微处理器,包含1GB RAM30GB的硬盘,预估售价为599欧元!

由于宏碁与惠普都非常小心寻求在迷你便携计算机中不与目前笔记本电脑产生销售冲突,因此都会以不同态度进入此市场。不过,宏碁在欧洲拥有Packard Bell品牌,将能让其放手一玩!(755字)

业界:SSD试水企业级存储


从SSD依旧昂贵的价格、应用的限制等方面综合评估,SSD在企业级存储中的大规模应用还为时尚早。但是还真有很多人愿意顶着高价偏偏选用它们的,这样的用户,都是崇尚环保并且用于尝试的。

  在IT消费产品领域,已经有笔记本电脑厂商开始选用SSD(固态硬盘)来替代传统硬盘。从2007年7月IBM宣布在刀片服务器中首次采用SSD,到2008年1月EMC在高端企业级存储产品Symmetrix DMX-4采用SSD,再到2008年6月,Sun在服务器和存储产品中也开始支持SSD,SSD开始登堂入室,从消费产品领域跨入到企业级应用中。但从SSD依旧昂贵的价格、应用的限制等方面综合评估,SSD在企业级存储中的大规模应用还为时尚早。

  优缺点都很鲜明

  SSD最大的优点就是速度快。SSD的速度至少比传统硬盘快1个数量级(10倍)。这也决定了SSD的应用定位——需要快速处理海量信息的应用,比如电子交易系统、实时数据处理、主机交易处理等,其影响时间可达到毫秒级。EMC中国研发中心副总经理、软件总监李映举例说:“某信用卡公司采用EMC基于SSD的Symmetrix DMX-4存储系统,将过去处理欺诈探测信息的速度提高了6倍。”除了速度快以外,SSD的优势还体现在:SSD的内部没有机械装置,因而不会出现机械故障,而且噪音低、能耗少,其能耗只有传统硬盘的1/5~1/6,符合绿色存储的发展趋势。

  在EMC之前,一些存储厂商已经把SSD应用于企业级存储阵列中,比如CURTISQbisys等。SSD突破了传统硬盘的性能瓶颈,并且价格逐渐走低,因而SSD开始从军用系统、高性能计算等领域逐步拓展到商业和企业应用环境。

  但是,SSD的缺点也显而易见,最突出的就是价格高。不可否认,SSD的价格正呈逐年下降趋势,但从目前的价格水平看,仍高出传统硬盘数倍。一个1TB的传统硬盘的价格约为550美元,而同样容量的SSD的价格可能超过1万美元。Sun虽然表示将在今年底时推出较低价格的SSD,但也不否认,即便如此,SSD和传统硬盘之间的价格差仍会十分明显。

  两种技术各取所需

  SSD根据采用的存储介质分为两类:一类采用Flash Memory存储芯片,简称Flash SSD;另一类则采用DRAM Memory存储芯片,简称DRAM SSD。

  Flash SSD主要用于消费类电子产品的存储器(如MP3、MP4、数码相机、手机等),也可用于移动存储(如U盘等)或工业标准尺寸的Flash SSD硬盘(如工控环境、军用环境等)。Flash SSD具有优异的读性能,而且Flash Memory是非易失性的存储介质,因此无需电源保护。Flash SSD的缺点在于写性能和耐久性较差。EMC Symmetrix DMX-4存储系统采用的就是Flash SSD。“在企业级存储中采用SSD,主要是为了解决存储性能问题。对于某些高端企业级客户来说,即使再大的缓存也不能从根本上解决存储性能的问题,只有采用SSD取代传统硬盘,才能满足对高存储性能的需求。”CURTIS公司莫桦介绍说,“SSD提供商STEC公司通过技术收购,使其大容量Zeus-IOPS Flash SSD的耐久性得到大幅度提升,并且在几年后500GB的SSD的价格有可能降至2000美元。如果这一天真的到来,那么当今的FC(光纤通道)磁盘就失去了存在的价值,传统磁盘工业将被颠覆。”

  作为存储领域的领先者,EMC必须提前对硬盘工业可能发生的巨变做好准备。李映表示:“EMC进入SSD领域是一个慎重的决定,一方面是看到用户有这方面的需求,另一方面也表明EMC对未来发展的判断具有前瞻性。”

  DRAM SSD采用SDRAM或DDR SDRAM作为存储介质,是易失性存储,所以DRAM SSD需要一直有电源保持供电。一台DRAM SSD设备内部除了I/O接口控制电路和DRAM Memory存储芯片板外,一般还包含为DRAM Memory存储芯片供电的锂电池、纠错电路,甚至还有在供电中断时用来保护DRAM中数据的备份磁盘。DRAM SSD的优点是读写性能同样优异,而且具有高可靠性和耐用性。其缺点是需要始终保持电源供给,以保证数据不丢失。

  近年来,Flash Memory存储芯片的容量直线上升,而价格在直线下降。如果有一天,当Flash SSD的价格与同等容量的传统硬盘相差无几时,Flash SSD有可能会全面取代传统磁盘。可以这样说,Flash SSD的市场目标是全面取代磁盘成为在线存储介质,而DRAM SSD的市场目标则是满足高端客户对极高存储性能的需求。

  可靠性有待证明

  SSD的性能及能耗优势,使得它在企业级存储中的应用开始受到重视。但目前只有EMC、Sun等少数厂商支持SSD,而SSD在普通商业领域中的应用才刚刚兴起,还需要大量的实践证明其可用性和可靠性。Iiluminata的咨询师John Webster表示:“我并不认为人们采用SSD的速度会比其他存储新技术更快。SSD供应商必须证明SSD是可靠的。”李映介绍说:“目前,EMC在SSD产品方面只有一家合作伙伴。经过我们的反复测试,只有这家厂商的SSD产品在可靠性方面能够满足企业级存储的需求。”
 
 
 
 
 

朗科发布国内首款SSD固态硬盘

日前,全球移动存储领导厂商朗科公司隆重发布了国内第一款采用闪存存储介质的SSD固态硬盘。

  日前,全球移动存储领导厂商朗科公司隆重发布了国内第一款采用闪存存储介质的SSD固态硬盘,在业内引起广泛关注。“SSD固态硬盘的出现是存储领域一个划时代的技术革新。从此闪存为介质的固态硬盘开始了它替代传统硬盘的伟大征程。”闪存盘之父,朗科公司总裁邓国顺表示。

  朗科公司是国内移动存储厂商中第一个推出SSD固态硬盘的企业,并一直是全球闪存应用的技术先驱。自1999年朗科公司发明全球第一款闪存盘以来,先后在闪存应用及移动存储领域累计申请发明专利达两百余项,覆盖全球几十个国家及地区,迄今已授权的发明专利达35件。

  SSD固态硬盘多项技术性能更加优越

  相比传统硬盘,SSD固态硬盘拥有明显的速度优势。据悉,朗科这款SSD固态硬盘读取数据的速度达到了180MB/S,写入数据的速度达到了100MB/S,比传统硬盘拥有数倍优势。搭载朗科SSD固态硬盘的笔记本从开机到出现windows XP桌面一共只用了13秒,而搭载传统硬盘的笔记本总共用了31秒,两者差距超过一半。

  其次,SSD固态硬盘防震抗摔,数据存储更安全。因为全部采用了闪存芯片作为存储介质,所以SSD固态存储器内部不存在任何机械部件,这样即使在高速移动甚至伴随翻转倾斜的情况下也不会影响到正常使用,而且在笔记本电脑发生意外掉落或与硬物碰撞时能够将数据丢失的可能性降到最小。

  另外,SSD固态硬盘功耗小、噪音低、发热量小。工作时静音(固态存储器因为没有机械马达和风扇,工作时噪音值为0分贝),正因为没有传统硬盘磁头与盘体之间的摩擦,因此它的发热量小、散热速度也快。

  朗科方面表示,在产品外形和尺寸上SSD完全可以做到与普通硬盘一致,包括2.5"、 1.8"等,甚至可以做得更小。SSD固态硬盘在重量方面更轻,与常规1.8英寸硬盘相比,重量轻20-30克,减少的重量有利于移动设备的便携性。朗科此次推出的SSD固态硬盘是2.5"产品,体积小巧,便于携带。

  SSD固态硬盘开始步入商业应用

  SSD固态硬盘优越的技术性能很快引起了各大电脑厂商及消费电子产品制造商的极大兴趣。据悉,目前包括三星、英特尔、朗科等厂商都已经发布了自己的固态硬盘。

  除了制造领域巨头云集之外,SSD固态硬盘的商业应用也已经迈开步伐。例如2007年下半年,苹果在MacBook Air中就以固态硬盘取代了传统标准型硬盘,华硕2007年推出的Eee PC,也采用了NAND Flash为储存媒介的固态硬盘。

  “用户也可以把它单独当作一个系统盘来使用。”朗科方面表示,人们将可以重温从386跳跃到奔腾3.0的感觉。

  不过,有业内人士担心,高昂的成本可能是固态硬盘迅速普及的拦路虎。与一个GB级别的容量相当的传统硬盘产品相比,固态硬盘的价格要高出10倍左右。

  对此,朗科有关人士表示,闪存芯片的价格历来呈现出指数下降的趋势,2001年8M闪存盘价格是999元,今天8G的闪存盘也不过几百元的价格。大容量SSD固态硬盘的成本未来两年内将大幅度下降,全面普及只是时间问题。      http://storage./446/8262446.shtml
