If possible, you'll want to go with the newer OCZ Vertex or Summit SSDs. The Core series did not have any internal cache and the controller used in those provided "iffy" performance. Most notably, frequent "pauses" while using the system. If you happen to already have the drive and just want to try it out, you won't hurt anything... but I wouldn't suggest that you purchase one. There is a huge difference in the different generations of SSDs.
