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

 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less money.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark popular with users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
