Edit2: Turned off all caching and random write IOPS are 1800 for queue of 1 and 4400 for queue of 32. Random read IOPS did not change. Will test on ICH9R later...
Yep, random writes are now within of Intel specs.
I didn't expect much change for random reads, though.

The latency sounds right for queue=1 though, since at 4K IOPS = 1s/4000=0.25ms.
NCQ?
Did you try on ICHxR instead of Adaptec?
