Hope it works! edit: The fix works, there is no more decrease in speed after waking from sleep. However, it seems like sequential reads have decreased by about 400mb/s. Used to be around 3200, now its 2800

Thanks for the download link. It worked for me, I have the file.

OS drives, including RAID volumes as OS drives, can loose some performance over time. But that seems a bit much to be related to that.

Did you ever run the trimcheck tool on that RAID array? I know I did at one time, but don't have a RAID 0 or 950's anymore. TRIM worked at that time. Just a thought, might not be the cause.

Also, CPU power saving options, and the chipset ASPM power saving options can affect performance of drives. Just going over other possible causes.

So you don't see any loss in performance in other areas, like 4K Read and Write, etc? What benchmark test did you run? What version of IRST are you using, just for the record.
