Hi, I'm about to get the first SSDs for my MacPro, and the reviews and postings about the OWC look very good . However, I'd like to use the SSDs in Raid0 arrays, and OWC recommends the RE models for this purpose, due to their 28% over-provisioning . After doing a little research, I noticed that OCZ is offering the Vertex 2 in both 28% and 7% over-provisioning versions, the VTX and VTXE(xtended), and they are pretty much the same price - yet OWC is charging quite a bit more for the RE drives compared to the non-RE version. While I'd rather buy from a trusted Mac vendor like OWC, I'm put off by the pricing policy; the additional warranty isn't of much concern to me, and the controller and other main components seem to be the same as in the Vertex 2 . Is there anything in particular that makes the OWC RE drives more Mac friendly ?
