Unexplained, Unpredictable Windows 7 64-bit slowdown

What are the full specs of that SSD drive? Model number? Have you done a firmware update?

This is the exact model I bought:
Newegg.com - ADATA S599 AS599S-128GM-C 2.5" 128GB SATA II Internal Solid State Drive (SSD)
Date of purchase was 1/21/2011

I have not done any firmware updates.

I will say, though, that before this problem started, the Windows Experience Index rated my SSD's R/W speed at 7.1. When I ran it the other day, after this problem started happening, it rated it at 7.5. I'm not sure if that makes a difference or not.

Thanks for the link. I imagine there's little hardware difference between the 128GB that I have and the 64GB that he's using, except for the memory cells. I will attempt a firmware upgrade tonight, see what happens. I'm not sure why it would take a year for this problem to develop, though.

Otherwise, I have a 640GB Mechanical sitting around, I'll toss that in and see if a system install on that disk will have the same problem. Try to narrow down which hardware groups I need to look at.

Not sure why it would take a year, either. Possibly just writing to the disk more has started to make the problem more prevalent.

Good idea about swapping drives out for testing hardware issues. Keep us updated on whether the firmware update helps or the drive swapping helps.

Well it's fixed. A firmware update did indeed solve the problem. However, the firmware update that solved it was to the MOTHERBOARD, not the drive. I did update both, but did the motherboard first, and that solved the problem. I've had this drive for a year, I'll never understand why it took a year for the mainboard to realize that "Hey! I need a firmware update!" Thank you both for your help!

No problem. Thanks for posting back your solution. It may help others who have similar problems. :)
