    Install took less than 5 minutes. 30 seconds to remove my PS5 hardcover. Another 30 seconds to remove the metal ssd housing door, another 30 seconds to remove the inner screw that secures the ssd in place, 30 seconds to install ssd, another 30 seconds to secure, 1 minute to close the housing and case. Job done

    Easy way to upgrade the storage for the PS5, It is pricey for 4tb but if you do play a lot of games and like go back and play them with out shifting data around this is one of the best options.

    Everyone I know skimps on the M.2 from the manufacturer only to clonezilla it to a new much larger M.2. I'm so guilty but before you order this lovely M.2 make sure you order the heatsink so you don't make it melty.

    Used this to increase the storage capacity and speed of my PS5. It did not disappoint. When used with a heat sink it also helps the console run cooler
