    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.

    Screaming fast , runs a little hot so you will need heat sync, but at this price point it’s an amazing deal.
