Anvil's Storage Utilities

There you go, those are mostly real results. Except the 32k and 128k randoms show a lot higher than they really are for some reason. (real results for your array should be less than 228MB/s for 32k and less than 920MB/s for 128k.)

Anvil - any idea why? QD1 RR 32k and 128k read iops must be less than QD1 RR 4k iops by definition but his result is showing much more? Is it a bug in the software?

it is not a bug, you're just misinterpreting the results. mb/s is iops*transfer size.

Nope didn't misinterpret anything.

You are not paying attention to what One_Hertz wrote. The problem is that the IOPS do not make sense. It makes no sense to have IOPS be higher for 32KB or 128KB blocks as compared to 4KB blocks (QD=1 for all cases).
