I've purchased 3 SSD drives from OWC in the past. All 3 failed within 6 months. These were their extreme performance 2.5" drive. The first was a purchase, the next two were failed replacements. When the 3rd one failed I told them I don't want another replacement I want my money back. They refused. While I like most of their other products, I'll never by another SSD from them again. I'm not convinced they know what they are doing nor do they take the time and engineering to produce a quality product. JMHO.
