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

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

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.


Poor
