SSD issue's

Hi

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 ;) 

Regards, Neil ;)

Since you installed Windows when your SSD was in IDE mode you cannot switch to AHCI mode without 1st editing the Windows Registry file.

After you edit the registry file reboot into BIOS and change SATA modes to AHCI.

The latest firmware version the Agility 3 is 2.22, which is what your drive is already on, so there's no need for you to update.

When you're done benchmark again with AS-SSD.

Don't forget to get the latest driver for AHCI mode after all of the stuff Dereck47 mentioned.

Hi again,

Thanks for your replies

I did the regedit thing ...well I must of done something. It was already on 0 value... but i still changed it to 0 :pt1cable:  and rebooted and changed bios to ahci and it worked without a BSOD!!

So bravo for that bit of advice.. spot on :D 

Here is my latest screenshot




Which is alot better than my original but no where near optimum... or is it for sata 2?

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 :ouch:  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.

Here's the link to the spec sheet of your drive: http://www.ocztechnology.com/res/manuals/OCZ_Agility3_P...

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.

The Asus M3N78-VM uses the NVidia GeForce 8200 chipset, which is not the greatest.
Microsoft's drivers are probably the best.

I didn't change any settings just opened and run ;) 


Can anyone point me in the direction of the AHCI drivers... do you need to know details of my PC to get the correct ones?



Thanks Guys

Those ATTO benchmark results are very low. You should easily be getting twice those speeds.

Connect the SSD to port SATA4 or SATA5 and re-test with ATTO.
See page 1-8 of your motherboard manual for the location of the ports.

Yeah, those results are still low. Sorry, I don't know what else to suggest.
Hopefully other Forum members will have ideas that will fix your problem.

Start saving to upgrade your motherboard/cpu to one that is Intel chipset based.

Thanks for your reply Dereck, I hope someone else can help also.

I do want a little better read/write speeds out of my £60 SSD but not sure I want to spend cash on a new CPU, motherboard and probably ram to do so.

Still no clearer on finding/installing AHCI drivers. I have found a AHCI driver from 2008, which will probably be older than what I have. Plus its a ROM file and not sure how to get it on my PC.

If AHCI drivers were the issue that would be a good start... but would they be slowing things so much.

Thanks for your support guys
