could have used some DRAM, stutters when booting.

Cheap price, fast read/write speeds, trusted brand name... whats not to like?


Good

A great value for a boot drive. The only thing that holds it back is the lack of a DRAM cache, but for the price, it is an excellent choice. I know many people who use this drive; for all of them, it has not caused a single problem.

A pretty decent SSD for a faster boot drive on a budget.


Good

With SATA-3 cables/controller/motherboard and in AHCI or Intel RST mode works just nice! Weight is really light and the case is fully aluminium. Yeah, memory type of this SSD is MLC, but still performs very well.


Average

4 years ago.

Quite slow speeds compared to it's other slightly more expensive competition. I can't recommend it. You get what you pay for I suppose.

 Frequently Asked Questions

 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.
