raid stripe size vs performance

[Adam Hough]

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).
