Vaio Z690 with SSDs - very slow in Windows 7

Hi everyone, I have a Vaio Z690 that is about 2 years old and it comes with the 64MB Samsung drives in Raid 0. The computer was ultrafast as you would expect until I installed Windows 7, when it then slowed to a crawl. The performance issue seems to be with the disks because their WEI score is extremely low (in the 3.x range) whereas the all the other components get a WEI in the 5.x range.

I have had two different computer guys look at it. They both reinstalled Windows 7, configured the drives as Raid 0 and updated all the drivers but this did not lead to any performance enhancement and said they could do no more. Also, they said they cannot add a new SSD because the Sony uses a proprietary connector.

Boot-up time literally takes 3 - 3.5 minutes. Opening Firefox or IE9 takes 6 or 7 seconds. The computer is extremely sluggish in general.

Does anyone have any ideas? I suspect there is a software or driver issue here involving the SSDs but for the life of me I can't figure out what it is.

I would appreciate any thoughts, otherwise I'll have to plunk down $1500 for a new SA.

 

Have you checked the Sony site to see if there is a BIOS update for your model? Might help.

 

For what it's worth, I have a Z590 w/ the same hard drive and no sluggishness under Win7, so I'd guess a software issue.
