Quick, Stable, But Not It's Rated Capacity

This drive was easy to install and has been the fastest external SSD I've ever used. I didn't test it as an internal drive, so I can't attest to the functionality of it's rated speed. I did fill it to 80% capacity and experienced no slow down. Only down-side is that it's capacity is rated to be 4TB, but it's actually 3.6TB .
