I just put together this new rig and my OCZ Agility 2 is running at a fraction of what is should be. I've tried enabling AHCI (Windows 7 was originally installed in IDE mode) and enabling TRIM, but with no serious improvement. Here's AS SSD benchmark with Marvel 9128 and ICH10R (tried both):
AHCI with Marvell 9128
AHCI with ICH10R
Here is the review by our own fearless leader: http://www.techpowerup.com/reviews/O..._120_GB/5.html
Looks like my speeds should be significantly higher. Alignment looks good from AS SSD and I've also used Paragon Alignment Tool to varify this. I'm currently running the OS from this drive if that makes a difference. I have not tried the sanitary erase prog mentioned in the other thread yet.
