It gives accurate readings with incompressible data, I don't know why you would say it does not. It simply tests with different data than what the drive is advertised for that is all.

AS SSD helps troubleshoot speed issues better than ATTO, when in comparison to other AS SSD benches of the same drive. It shows the alignment, if he is using IDE, AHCI, or RAID mode, and the firmware version as well. These things are far more important than showing what the compressible data test shows to help troubleshoot the issues for him. You can see that the drive is lacking somewhere just by quickly comparing the overall score to a similar drive with AS SSD.

It is probably just from power saving features in the chipset based on the speeds for each test.

We're having a misunderstanding. I was showing him his ATTO score to show that his drive was achieving optimal performance, as AS-SSD uses incompressible data and is a poor indicator of peak theoretical performance on SandForce devices. If his drive were not aligned, ATTO would not have delivered those results.

The SATA ports are running in AHCI and the drive is running FW 1.3.3

I've made sure it's connected to the Intel controlled SATA ports and my power options are set to high performance, with hibernation disabled.
