Thanks. We'll let you know when a new response is added.

I’m sure somebody else will post a more detailed explanation about this, but in a few words, RAID 1 is a “standard” RAID level, in which you create mirrors of disks, and RAID 10 (which is actually 1+0) is a nested level in which you create a mirror of disks and then you stripe those mirrors (i.e. you apply a second level, in this case RAID 0). It is called a stripe of mirrors.

    Carlosdl is correct, RAID10 (a.k.a. RAID 1+0) is a stripe of mirrors; not to be confused with RAID 0+1, which is a mirror of stripes. See this section of the Wikipedia entry for more info.
