Wikipedia has a decent write up of how the Linux MD RAID 10 works. http://en.wikipedia.org/wiki/Non-standard_RAID_levels#Linux_MD_RAID_10 Linux MD RAID10 (RAID10) implements a general RAID driver that defaults to a standard RAID 1+0 with four drives, but can have any number of drives. MD RAID10 can run striped and mirrored with only two drives with the f2 layout (mirroring with striped reads, normal Linux software RAID 1 does not stripe reads, but can read in parallel).
