complete garbage, needs a firmware update, freezes and stutters for 5-20 seconds every few minutes, makes for anything but the most basic of internet browsing/youtube checking impossible or mind numbingly annoying to do.

Still better than HDD in most cases, but is probably the worst SSD around. Definitely not for boot/OS as it doesn't have dram. Write speeds will disappoint once it fills up (after 50%). It gets to 30 MB/s writing, much slower than HDD. I even got 15 MB/s writes when 75% was full. But good for gaming with its good read speed—Dec '20

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.

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.

I don't recommend this even for a budget build. DO NOT use it as a system drive. Yes it'll be faster than a hard disk but the reliability is questionable. Buy yourself a dram ssd for system drive, don't cheap out on it this is very important. Terrible write speed
