This isn't exactly mining-specific, but I'm going to be putting together a server that will do lots of transactions and need a recommendation on an SSD.

I want to start small with a single 120GB 6Gb/s SSD that's not too expensive, and then later go to a RAID 5 with 3 oif those SSD's and a hardware controller.  Further down the road I could think about SLC enterprise SSD's, but I need something to get me going that will be fast with transactions and not too expensive

Drives I'm considering:
* Patriot Pyro
* OCZ Vertex 3
* Crucial M4
* Intel 510

Suggestions?
