Seems like I'm getting pretty poor performance on my Vertex 2E 60Gb:






I've no idea what AHCI is :confused:, but I'll read up on it and see if it can help me get better performance.

Getting pretty abysmal Read speeds on my 90GB Vertex 2E. I'm pretty sure that the Read speed should be faster than Write!

I've followed the instructions on the SSD Windows 7 Tweaks guide but if anything I lost a couple of MB/s speed!

EDIT: enabled AHCI

Sandforce controllers store data in compressed forms, meaning less data needs to be written. This means less write cycles are used, and the more the data is compressed, the faster it can be read from or written to NAND.
Atto = Best case compression. AS-SSD = Worst case compression. Real performance is somewhere in the middle.

In addition to this, bear in mind that running a lot of benchmarks in a short space of time will affect its performance. Give it a few nights of light use and idling to let the Garbage Collect routines work and you might see speeds pick up a bit.
