楼主要是不发这贴，我还真以为RAID0+1和RAID1+0一样呢？这么看来，还是RAID1+0要好于RAID0+1 。只可惜我没有接触过RAID，继续期待您的精彩！ 刚才查到这个：http://wangxb.blog.51cto.com/89889/16560，也是关于RAID0+1和RAID1+0的，感觉也不错！双收了。 还有个问题想请教下，到底RAID10=RAID1+0呢，还是RAID10=RAID0+1 ？ 找到答案了：RAID10=RAID1+0，RAID01=RAID0=1 RAID 10 RAID 1+0 (or 10) is a mirrored data set (RAID 1) which is then striped (RAID 0), hence the "1+0" name. A RAID 1+0 array requires a minimum of four drives – two mirrored drives to hold half of the striped data, plus another two mirrored for the other half of the data. In Linux, MD RAID 10 is a non-nested RAID type like RAID 1 that only requires a minimum of two drives and may give read performance on the level of RAID 0. RAID 01 RAID 0+1 (or 01) is a striped data set (RAID 0) which is then mirrored (RAID 1). A RAID 0+1 array requires a minimum of four drives: two to hold the striped data, plus another two to mirror the first pair. It provides best RW performance. |
