I have OWC's Mercury Extreme Pro 3G and Mercury Extreme Pro 6G drive and have no issues. OWC is a fantastic retailer with responsive and considerate customer support. Not to mention an industry leading 5 year warranty. I also have three (3) OCZ Vertex 3 MAX IOPs. These systems are not perfectly stable, but I'm contending with 24/7 operation in Windows 7 x64 with RAM at 1866MHz and heavy disk activity. Not to mention that I have preview video card drivers, AHCI hack, beta WMC tuner drivers. When one of those systems goes down, its hard to honestly point the finger at OCZ.
