Using the RAPID option with 16 G of ram


3 days ago.

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.
