In the Web-Server pattern the controllers again form two groups with the same behavior when they work with the RAID0 array. This time the AAR-1420SA has moved from the second group into the group that increases performance at long queue depths. Moreover, this controller proves to be the best at long queue depths whereas the more expensive ASR-44300 wins at small depths only. The AAR-2820SA has low results again.

We’ve got the same two groups with the RAID10, too. The ASR-44300 is unrivalled in this test because the pattern contains read requests only.

There are no changes with the RAID5: the ASR-3405 is far better than its opponent.

The overall rating depends but slightly on the array type: the ASR-44300, AAR-1430SA and AAR1420SA are in the lead with very similar ratings. They are followed by the ASR-3405. The AAR-2820SA takes last places, being considerably slower than the others.
