A note:
G-Skill Titan, Super Talent ME, OCZ Vertex, (?) Patriot Warp 3 were supposed to be the same drive.

Only OCZ mentiones cache. So either these are different (I doubt it) or the others just don't talk about features most users don't understand (well, unusual too ).

I put the question mark on Patriot because it's listed to have 240 MB/s reads.
