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

One of the worse SSDs around, still miles and miles better than booting from a Hard Drive. It doesn't have a NAND cache which is unfortunate and might hurt longevity. Pricewise this is also probably the cheapest you can find which is why it's so popular. Do not get the 120GB version though since SSDs slow down massively once they get filled up.

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
