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]

The 240GB Sandisk Extreme Pro uses the same controller and NAND as its 13 months younger predecessor, the Extreme II. Comparing the Extreme II and Extreme Pro shows that average performance has increased by 10% but peak performance remains broadly unchanged. The Pro features an improved nCache which uses an SLC buffer to cache writes prior to writing them to the slower MLC NAND. In order to benefit from this improved caching, huge amounts of data need to be written for extended periods, an unlikely consumer scenario. Comparing core performance between the Samsung 840 Evo and Extreme Pro shows that the Extreme Pro averages around 12% faster than the Evo. The Extreme Pro also has a 10 year warranty but I wonder if SATA 3 will even be around at that time. Although the Extreme Pro has a superb performance profile it's not a game changer. [Jun '14 SSDrivePro]
