Yeh mine is the same as yours, although I know my drive supports TRIM. OCZ however, inform me that my drive does not need TRIM or GC since the SandForce controllers do it on-the-fly.
I know another SSD owner who has the same drive as me, just a smaller size, but he's been using it pretty heavily (film editing) for the past few months and says he's benchmarked his and hasn't had any slowdown at all. Also several people on the OCZ forums show no slow-down with their SandForce controller drives, hence Im not too bothered about TRIM etc any more. Just gonna use it and see how things go!
