In the end though I think it's a judgement call, based on your trust of the company producing the product (much like anything). OCZ seems to have put together a nice drive, the question is whether they approach the "enterprise" class devices which are built to account for write degredation over time. I doubt you'll find much hard evidence either way without some insider perspective. Good luck!
