I have recently bought a OCZ Agility 3 2.5" 90GB SSD (I was told to go for the M4 series but cash and GB where a factor) and I have installed Windows 7 onto it with a partitioned 500GB HDD for pics, films etc etc...
I have read the instructions which tells me that SATA 3 is backward compatible, which is a result due to the fact I have a SATA 2 Board. But it does run slower like it also told me.
Speed being my main issue here is a screenshot..
Should it be that slow even on SATA 2 when it states 525mb/s read and 500mb/s write?
I have also tried running my pc in AHCI mode with APAI 2.0 support (I think it was called) but when I do that in the BIOS I get a BSOD after the Windows logo loading screen. So I cant even update the firmware with the OCZ toolbox as it needs to be run in AHCI mode rather than SATA.
Would the fact that I can only run the SSD in sata mode make the huge difference in performance or is it the lack of updated firmware?
Sorry for any laymen questions... hope you guys can shed some light
I did the regedit thing ...well I must of done something. It was already on 0 value... but i still changed it to 0 and rebooted and changed bios to ahci and it worked without a BSOD!!
So bravo for that bit of advice.. spot on
Here is my latest screenshot
Which is alot better than my original but no where near optimum... or is it for sata 2?
Don't forget to get the latest driver for AHCI mode after all of the stuff Dereck47 mentioned.
Your breaking my heart with that line.... I did a google search, ended up putting some downloader on my pc with all kinds of stuff that will end up hurting my pc and paying you tech heads another visit in 1 months time. And even when I got it, I still didn't get the dam AHCI driver.
Is there somewhere I can get them? Maybe a site without porn pop ups... I don't mind them but the wife don't appreciate them to much and can the driver be installed whilst in windows?
Thanks again Guys

Advertised AS-SSD speeds for your drive are "up to" 180MB/s Read and 105MB/s Write on a SATA 3 (6Gb/s) port.
You're benchmark indicates you're getting 73% of advertised Reads and 50% of advertised Writes.
Advertised speeds for your drive on a SATA 2 (3Gb/s) port are "up to" 280MB/s Read and 260MB/s Write using ATTO benchmark software.
Benchmark with ATTO and see what your results are.
If you are getting close to advertised speeds with ATTO then that is an indicator the your AS-SSD results are also good.
I have an Agility 3 60 gb, on sata 2, with AHCI on, with frimware 2.22 (latest) and it gets on CrystalMark:
Seq R/W = ~200MB/sec
4k Read = around 30-40MB/sec
4k write = around 120MB/sec
they arent that much slower on sata 2, but it shouldn't be as low as you are getting. I might blame the msahci driver file. I have intel controllers for SATA on my board (an ECS G31 chipset), which board do you have and do you know which controller you are using? Maybe we could find you a better driver choice.
