Contrary to my own recommendations in recent months, I'm considering a couple of OCZ Vertex 4 SSDs. Newegg has the 256GB drives on for a great deal right now. Anyone else here using these? Any experiences good, bad or ugly? From what I've read they have an innovative performance mode that uses the dual cell MLC NAND like single cell SLC NAND until the drive gets to 50% and then it utilizes some garbage collection to try and maintain this in increasingly smaller 50% chunks until the drive is full. Seems like a nice idea. I'm wondering about failure rates in particular, but I suspect the population here is probably too small to gauge that accurately. Any opinions or experiences are welcome!
