    Got it on sale for $139.99 for an early Black friday sale. Just as good as thr Sabrent Rocket but cheaper. Currently I’m using it for my ROG Ally and can now download more than 4 games to my system. However I recommend buying and installing the SSD immediately instead of waiting 3 months later.

    I purchased this storage to replace the factory storage in my Surface Pro 11. Overall, it’s an exact fit, and is faster than the stock unit. Great buy for upgrading!

    So far it has held up to the specs it was advertised. Have reached both the right and read speeds in my tablet just fine. Does run a little hot but that's to be expected for the type of drive that it is.

    Very good compact SSD. The best amount of storage for price I can get for my Steam Deck. The installation was definitely difficult as a first timer, but it worked out well for me. Definitely the best 4x4 M.2 SSD you can get to upgrade your Steam Deck storage.

    Fast & works well with my steam deck, it's a bit too expensive for what it is though. Setup was easy, disassemble the steam deck, put it in the slot, reinstall steamos & you're good to go.

    This has worked great for my needs. I needed more storage on my Ally, and the install was fairly easy. I am able to fit pretty much every game I own on steam.
