Summary: I love crucial as a company. They have always been very supportive and I have typically been very happy with all crucial products. The V4 is the exception to that rule. My WD 72000 RPM HDD benchmarks a write speed that is DOUBLE the benchmark for my V4. I purchased the V4 to speed up my operating system. That has proved to be a massive failure.
Used this to run my OS and now the computer boots so fast!

Summary: Purchased this to run Windows only. I have a larger hard drive for files/storage. This thing made my computer run so much faster its insane. It boots up to Windows 7/8.1 SO much faster than my non SSD hard drive. I'm at the login screen in less than 20 seconds. Highly recommended!!
