Great performance for the price point. Best for early-mid tier builds. Should not use for high end gaming. Average warranty seen on most products of type. Good reliability and very nice speed. Average user will see significant improvement compared to most drives. Again not for performance tuned systems as drive will be the slowdown point for these builds.

Decent pricing for a speedy 1TB SSD, Only drive needed for a gaming pc.

Amazing read/write speeds. This SSD alone is what made me want to ditch hard drives altogether. Running Windows on this SSD guarantees a boot time of 30 seconds or less from my experience. Seriously, if you are using a HDD, switch to this right away.

great nvme drive, budget at fast speeds! works well for my game development work.

Blazing fast speed, great price for the capacity! This loads everything fast and is all you really need if you are a gamer. One con I have with this is that the TBW is 220. However this does not affect me since I do not do heavy work or art. 220 TBW is a lot for me, and I will probably never reach that in 30 years! Overall this is a great drive!
