    Massive Store in a Small Drive

    I've had this drive installed for about three weeks now and have nothing negative to say about it. It's fast and has tons of storage. Exactly what you'd expect of a small factor SSD.

    Perfect

    Great piece of hardware, as a first timer in replacing SSD’s it was hard to figure out data copying/transfer but it works perfect and it’s honestly shocking how they manage to get 2TB on such a tiny SSD (mines 1.96 to be exact).

    The baddest ssd for handheld gaming devices.

    OMG. This is the fastest m.2 2230 ssd ever. Slap this bad boy in my Lenovo Legion Go and it transformed it into a beast. The read/write speed exceeds expectations. A must buy. Just a little expensive but it’s definitely worth it. Outperforms all m.2 2230 on the market. First picture is the Speedtest of the ssd inside the Legion go and the Second picture is the Speedtest of the WD black SN 770M

    Storage and speed champion

    I bought this as a storage upgrade for my Steam Deck and it does not disappoint, plenty of storage for my games and a nice jump in loading compared to the storage it came with. Overall it’s perfect for those with large game libraries or those that want a good jump in system response.
