Promise FastTrak TX4200 4-Port Serial ATA RAID Controller Review (page 5)

Now, let’s examine the performance of the four-disk RAID0.

The RAID0 seems to react to enabled TCQ in the same manner no matter how many drives it is comprised of: it gets a nice read speed bonus at long request queue depths, but becomes worse than with disabled TCQ at writing.

RAID10 is the most complex array type for the controller.

The controller seems to have found this mode too difficult: the table of efficiency is almost all red. We don’t want to make any hasty conclusions, though. This is just our first pattern, and many are yet waiting their turn.
