Got this as a boot drive/non game storage drive. It works as intended.

[This review was collected as part of a promotion.] Of course, plopping a new SSD in is never hard to do, and this was no different - quick easy installation and no comparability issues w my Frankensteined desktop and definitely no overheating either. I actually didn’t realize I had purchased the 1 TB and meant to get a 2TB, but it got the job done WELL and I can shove this one into my PlayStation 5 (it’s above the recommended specs )when I upgrade. Surprisingly well performing drive for what it is, MM790 is definitely the way to go in the series, you won’t be disappointed.
