I have not done any testing with the md native RAID10 implementations,
so perhaps there are some other advantages, but have you tried setting
up your 4 drives as a RAID 0 made up of a pair of RAID1s?
I have had very good performance in this configuration - reads and
writes of over 140MB/s for 4 x 7200 SATA.

Richard
