terrible performance. absolutely unusable as a main drive, so much stuttering, freezing and slow loading speeds


Terrible

5 months ago.

OS (win10 and linux mint 19) freezes and stutters for a few seconds when installed on this SSD.


Average

Cheap drive that is suitable for gaming, but performs poorly in Windows and can stutter/freeze with heavy usage. Kingston should release a new firmware to address these issues.


Terrible

2 days ago.

Poor write performance, its fast when its empty ~ 200MB/s, however when it passes 20%, it becomes terrible, about 40-50MB/s, on occasion it drops below 10. On linux its useless, ubuntu 18 freezes every few minutes.
