Great storage device

[This review was collected as part of a promotion.] What a great nvme storage device! I have been using it for over a year and in this whole time, I have no zero issues. It also runs very fast. All my apps and games that I've installed on it open up quickly. Despite the room being warm, it also runs cool. It's been very efficient. I wish I had gone with a bigger size storage with how big apps and games have gotten. Unfortunately prices have gone way too high on all storage devices, but I would still trust these Samsung ones. Not only is the product itself good, the Samsung software called Samsung Magician is very helpful to see how it's doing and how much you've used it. Giving you a heads up when you're starting to get errors or life expectancy is starting to end. Overall this is a great product and I'd recommend it.

Solid performance in SFF Build

[This review was collected as part of a promotion.] Bought one for my mini ITX build about a year and a half ago. Ssd performs very reliably, with good speeds for gaming and real-time streaming of creative assets. Functions extremely well, even with the more restrictive airflow of a small case. Like it so much I bought a second one to add in shortly after.

No compatibility issues were detected at anytime after installing it.
