Trying to decipher my SSD performance
I had an SSD sitting around that I put in my new HP Envy 4t. It is a Crucial M4 256 GB. It went in (with part of the bracket removed). Performance was excellent, but I figured I'd be better off getting a thinner drive and giving this one to my wife for her laptop....since it can easily handle regular thickness SSDs.
The drive I bought for me is a Corsair Force 3 240 GB. Now, I know that rated speeds are mostly marketing drivel, but I'm seeing a huge difference in read speeds between the two. Everything else is identical...computer, OS, and even driver versions.
So, is what I'm seeing normal, to be expected, or is something going on with my Corsair drive. I'm getting less than half of the rated speeds.

DeaconFrost , It's the firmware .
Trim does not work on ALL Sandfarce 22xx series controller drives . I have two SanDisk drives ( a 120 & a 480 ) with the same SF controller with the same issues .
It appears that Corsair is the first manufacturer to release the 5.03 based firmware for their drives that fixes Trim . That said I have already read that the 5.03 firmware still has I-O speed issues .
I have been advised by SanDisk that they are not going to issue a 5.03 based firmware for their drives , that they are validating version 5.04 and expect to release a 5.04 version in "about a month" . This deal is a sad story that has been going on for months .
This Tweaktown article explains the issue about as well as I have seen :

This notice is for the new firmware :
