The Mushkin Reactor features the same Silicon Motion SM2246EN controller found on both the Crucial BX100 and the Transcend SSD370. All three drives also feature Micron MLC NAND and consequently they all share a similar (and strong) performance profile. These drives were the last batch (early 2015) of budget drives to utilize MLC rather than TLC NAND and as a result they all have reasonably strong sustained write speeds. The more recent trend for budget drives is to utilize a small SLC write cache coupled with TLC NAND, a combination which results in severe write speed degradation upon cache exhaustion. The Mushkin Reactor doesn’t have this problem and both the 500GB and 1TB Reactors only lag the market leading 850 Evo slightly on performance. At today’s prices the 1TB Reactor offers better value for money than the market leading Samsung 850 Evo (compare them). See the current market leaders here. [May '16 SSDrivePro]

 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.
