The storage industry tends to use "RAID 1+0" when they specifically
refer to the older striped sets of mirrors. RAID 10, as implemented
under Linux is also found in some high end RAID controllers. Among
other things, it will allow you to have a RAID set with an odd number of
devices, and ensure that all of the stripes are on two different disks.
The description of Linux RAID10 on the wikipedia "nested raid levels",
referred to by zGreenfelder, was probably written by someone unfamiliar
with the topic. I'm not able substantiate a number of the claims made
therein. I wouldn't rely on that information.
