OCZ Vertex2, Team Group Xtreem and Corsair Force all use the same SandForce controller. Pretty much the same speed (from my limited look anyway)-
Yeah, I know, slightly different sizes in the tests, but sometimes you cant find the exact set of benchmarks you want....
OCZ Vertex 2 is a lot faster than the OCZ Solid 2.
OCZ RevoDrive has no TRIM.
It would come down to OCZ Vertex2, Team Group Xtreem and Corsair Force for me anyway. I wouldnt get a SSD with no TRIM, and the Solid 2 is quite a bit slower than the Vertex 2.
I'd probably go for the OCZ Vertex 2, but without doing some more serious digging I cant be 100% sure. Price could make a major difference as well.
