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 '15SSDrivePro]
The 250GB Crucial MX200 is successor to the hugely successful MX100. Both drives use the same NAND and controller but the new MX200 features Dynamic Write Acceleration (DWA) which is a new dynamically sized SLC cache. Samsung were the first to introduce SLC caching on the 840 Evo nearly two years ago so Crucial are somewhat late to the party. SLC caches generally only help performance in corner case real word scenarios and benchmarks. I prefer drives without SLC caches because they offer more consistent and sustainable real world IO. Comparing the MX100 and MX200 shows that the newer MX200 has a significantly faster peak write speed which is of course explained by the new DWA cache. Price is the deciding factor between the MX100 and MX200 so although the MX200 isn't priced aggressively yet, it will almost certainly move up the value rankings when retailers build stocks and subsequently cut prices.
