just bought it, amazing product well done team

I've had almost no issues with this SSD, it's very fast, has a large enough storage capacity, and fits just fine in my machine. The only issue that I'm taking away from it is that it won't allow you to measure the RAPID mode as it's considered cached and so I don't know how much of a performance boost it actually provides.

Used Samsung software with this SSD 850 pro 512 and it is lightning fast. Basically no load time for the most recent AAA titles. Because of the settings I have with Samsung magic the benchmark does not pick it up... but trust me it is fast and worth every penny.
