The Adata Premier SP610 sports a Silicon Motion SM2246EN controller coupled with 20nm Micron flash memory, a similar combination to Crucial's recent BX100 which uses slightly slower 16nm NAND. Comparing the 256GB versions of the BX100 and SP610 shows that although the two drives are fairly evenly matched, the SP610 edges ahead in most categories (so far I have only seen only 10 samples of the SP610 so this may change with time). Although comparing the SP610 and Samsung 850 Evo highlights relatively low write speeds on the SP610 it also shows that the Adata Premier SP610 isn't far behind the market leading Evo. The SP610 has a respectable performance profile and, at current prices it's one of the best value for money SSDs available. [Mar '15 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 popular with users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
