    This Product was very easy to install if you are confident in your dexterity with small pieces. Make sure you back up to the cloud 1st before you attempt this and make a recovery USB drive with Windows 10 or 11 on it if you are replacing your primary Operating system drive if not then this should plug in without any problem. if you do not want to attempt to replace your OS drive then hire Geek Squad to do it for you.

    I upgraded my games drive from a traditional hard drive to this drive and it's lightyears faster than my old spinning rust. I used to have enough time to get up and go get a drink my my games were loading and it's down to seconds.
