RAID 0 Perf. Degradation - P8P67 PRO

post #1 of 4
Thread Starter 
Hello-

Currently I have (2x) WD6402AAEX in RAID 0 with a 64kb stripe size (640 GB x 2). They are on the Intel RAID controller.

I have Windows 7 x64.

I have Intel Rapid Storage Technology 10.1.

Check Disk didn't find any errors.

HD Tune health test didn't find any errors (and took 90 minutes to complete).

C States are on - ASUS says that having them off can cause flaky HDD performance.
---------------------------------------------------------------------------




The installation went fine. I've been running it no problem since the day these boards were released. Recently though, I've noticed that the computer has become very choppy. Pause-go-pause-go, etc.

So I run a couple HDD benchmarks and find out that my average speeds are 1/10th of what they use to be, and are in fact dropping to 0, then back to full, repeatedly.

Upon rebooting there is a screen that shows my RAID array, and drive #2 says "An error has occurred." Intel Rapid Storage Technology also says that drive #2 failed - AND, that my RAID array has failed. If it's failed, how am I here, typing on it?

Also, if drive #2 failed, why can I run a check disk and HD Tune test and get no errors?

These are on the Intel SATA 3 (6 gb/s). In the SATA section of the BIOS it confirms that they are indeed in the SATA 3 (6 gb/s) ports. So I shouldn't be effected by port degradation? Unless Intel was wrong, and the SATA 3 ports degrade as well.



-------------------------------------------------------------------------


What I've tried:

Upgrading from Intel Rapid Storage Technology 10.0 (Came with the board) to 10.1 - No difference.

Switching the HDD's to other ports on the board, including the Intel SATA 2's - No difference

Check Disk - No errors found

HD Tune health check - No errors found

-------------------------------------------------------------------------------




So either:
1) One of my drives is crap. Doesn't seem to be the case since I've checked it.
2) The P8P67 PRO RAID controller is crap.
OR 3) Even the SATA 3 ports degrade on these boards.


Also, I know some people are going to suggest reinstalling Windows. However, if I go that route, what's to stop this from happening again a month from now? I'd like to know the root cause of the problem.








Thanks.

Swapped the cables out- This seem more normal? Feels snappier, anyway.







EDIT- here's this shot as well. 4k and 512k seem abysmal.

Also- Intel Rapid Storage Technology is still reporting drive #2 as having failed, even after I reset its status to normal. It went back to a failed report after ~30 minutes. What do I make of this?
