Recently purchased an OCZ Vertex 2 120gb off the MM and the other user had read/write speeds in the region of 270mb/s. However I ran the same benchmark and this is all I could manage:

I've set the drive in AHCI mode and ran the OCZ SSD tweak tool, not really sure what the problem could be? Motherboard is an Asus P5Q Deluxe.

Any help will be appreciated, thanks.
 
Have just done the same tests on a Vertex 2E on this PC - Asus P5K and got the following;

This is my OS drive, I had a browser streaming internet radio and a bunch of other programs also open.

Which Windows are you using? Have you done a manual Trim / Garbage Collection after loading it full of stuff?
 
Using Windows 7 Professional 64bit.

Nope I haven't done either, how would I go about doing that? (Sorry I'm a newbie with SSD's)
 
ok, Win 7 does Trim automatically I think - as long as its enabled. I have a feeling Windows Experience Index will turn it on after its scanned your machine.

You can check in Command Prompt by entering the following command;
fsutil behavior query DisableDeleteNotify

If that returns 0, it means Windows will send Trim to the drive... (command wont change the current setting, just tells you what it is).

Theres a stack of info on the OCZ forums as well for tweaks and tuning stuff.
 
Check SSDLife, says trim is enabled and that command returned 0.

I'll check out OCZ Forum for some tweaks.

Thanks for your help :)

Ensure the drive is connected to an Intel SATA port (the red ones) and not a Silicon Image port (the orange ones).
