Conclusion 
Average Bench 84.6%

There's nothing inherently wrong with it. It does what it's supposed to do, it's M.2. The reason I chose this at the time was because I trusted the manufacturing tolerances of Micron, and I thought that other brands were overrated. It saves space, because it can be mounted directly onto the motherboard, in one way or the other. Of course...If I had just waited a little longer I could have bought the new MX500 series SSD, but they don't have any M.2 format drives released yet and there isn't much of significant difference; which is a higher read speed of 560 MB/s and 5 year warranty. The 3 year warranty and read speed of 530 MB/s is just fine! [Dec '17 morahman7vn]

 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.
