    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.

    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.

    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

    Works great, no issues. This is backwards compatible for older motherboards, using it with an older pcie v3.0 slot and it works just fine but it is a bit slower due to the bus limitations.

    It's fast and has the quality you'd expect from WD. It does run hot because its PCIE gen 4 so I had to put a heatsink on mine.

    Upgrades from a 2TB Seagate drive using QLC. Totally worth the money as when a QLC drive is like 70% full they become trash. I am talking like 127MB/S read write.
