Slower SSD performance with official drivers

scorpian007 · 10 Oct 2010

Hi,

I had been tearing my hair out for the last 2 days trying to work out why my SSD performance was slower than my previous computer (Q9300, GA-EP41-UD3L with no AHCI, 4GB DDR2 RAM) and realised that it was the SATA drivers that came with my motherboard. As soon as I went back to the Windows default AHCI SATA drivers my read/write speeds were about 280MB/270MB per sec. once I installed the Intel ICH10R drivers and the Marvel SATA 3 drivers, my performance dropped to about 240MB/235MB per sec (This is using ATTO Benchmark)

Anyone notice this and is there a solution for this problem?

P.S. It also appears that the Intel/Marvel drivers do not support the TRIM command as when I run a program to force this to happen, the drive does nothing (whereas it works with the default drivers)

Hello Scorpian, and welcome to Seven Forums.

You might give the 10.0.0.143 beta Intel AHCI SATA drivers a try to see how it works for. It supports TRIM. I got better performance with my SSD with this one.

The latest official WHQL 9.6.0.1014 Intel AHCI SATA drivers (Intel Rapid Storage Technology) also supports TRIM, but it not the latest version as the one above.

Hope this helps,
Shawn

The first link goes to an auto back up tutorial? Second one seems ok.

Thanks so much for that. Installed the Intel driver and its working great!

You're most welcome Scorpian. That's great news. Which Intel driver version did you use?

I'm running the Beta at the moment and it is much quicker than the old Intel driver. ATTO Benchmark has the read/write speeds back upto where they should be and like you said, TRIM works! :) Now all I have to do is overclock the CPU and it should all be sweet.

Again, thanks a lot for the help!
