I plan to be installing 2 new OCZ vertex 3's (the 120gb models) in raid 0, in a new system come Christmas day or the day after. Before the trim junkies jump in, its been proven that trim and garbage collection end up providing the same benefit, just done differently. I would provide link to the persons posts, which was in the TH forums some 2 or 3 months ago, but I don't have a lot of time to go out and find the post right now.
So if you have two of any size OCZ vertex 3's in a raid 0 set up, please post the final strip size you went with. I'm thinking ether 64 or the 128 are going to be the best course of action.
