    When I needed more storage for my Steam library, this stick fit the bill. M.2 prices continue to fall, definitely worth the upgrade if your machine has a slot.

    Read/write performance is top notch. A little bit cheaper than similar drives due to no heat sink. Most motherboards come with heatsinks with m.2 drives so is usually a non issue.

    This was a great addition to my PS5! These games take up so much space that this is the perfect solution. 4tb with super fast loading times has been a game changer.
