Re: W520 SATA III 6Gb/s SSD suddenly running at SATA II 3Gb/s?

You could revert to the older BIOS as a test to see if that is the case...

Re: W520 SATA III 6Gb/s SSD suddenly running at SATA II 3Gb/s?

I used the bios update tool and flashed the bios, no change.

I might clone all my data off the SSD, install a fresh copy of windows back onto it and see if its maybe a driver or windows issue.

@webo

 

He said a Vertex3. 
I thought you had an Agility3?

You're right, for some reason I thought mine was a Vertex.

I doubt there's much in it Webo anyway.

 

To the OP can you post benchmarks of the drives in sata3 and now in sata2?
Curious what the difference previously and now.

Luckily I had an old benchmark from back when I first intalled the drive.

 

Here it is from when I first installed the drive and it was operating correctly in SATA III mode.

 

And here it is now running in SATA II.

I rolled back to BIOS version 1.36.  Still running at 3Gb/s so we can rule that out.

The solution is probably somewhere on the OCZ forum...

I ran crystalmark on my 120GB Vertex3 in my W510.

I was getting better results than you, do you think there's maybe a problem with your drive?

 

Have you made all the relevant windows changes?

Those write speeds are horrendous. Even my old Sandforce SF-1200 based drive gets nearly double your best write speed (275MB/s).
