What size are you looking at getting? I've had Gskill and Crucial and both have run flawlessly. Check that-the original Gskill I got was first generation and had a firmware problem where the SSD bricked after 6 months of use. I contacted Gskill and had a new replacement free. My wife still uses that one and it's still being used daily in my wife's PC and is over 3 years old now. The Crucial I have is the M4 256gb and is a little over a year in use. With some of the problems that Sandforce firmware had a while ago I just didn't trust getting an SSD with their firmware. That's been resolved now, but I can deffinitely attest to Gskill quality and service and Crucial reliability as well.
