The adapter is easy to install, and the necessary BIOS update was very simple. I deducted one star because it blocked the Wi-Fi slot. I had to sand down the protruding pins on the back of the adapter so it could be mounted over the existing Wi-Fi card. I also deducted another star because I had to remove the heatsinks from all four SSDs, as the slots are so close together that only very basic adhesive heatsinks will fit.
