Lots of people complain about the lack of dram, but given the price in my region, this beats most competitors.

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.

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.

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.

 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 the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
