Fits great in the Alienware m18 R1 - I was looking for additional storage for my now aging gaming computer and found this ssd that works great as game storage and has been super reliable and easy to install.

works great - Needed the small form factor for an ASUS Z13 and this worked great, a little pricey, but got a good deal and prices are already going up. Get it while you can.
