The Sandisk Extreme II uses the 88SS9187-BLD2 controller, Marvel's latest, and Sandisk's own 19MM MLC Memory. On paper this makes an extremely good combination and the benchmarks agree. The Extreme II scored an impressive 1143 in the server orientated AS SSD Benchmark putting it amongst the more capable server drives. In terms of real world consumer performance the Extreme II also fared well achieving a real world speed index score of 570.5 MB/s, amongst the top three scores we have seen to date. The Extreme II has everything going for it apart from its price which is currently significantly above average and hurting its value rating. Because the Extreme is the newest SSD we have in our group test we expect prices will drop with time. Until then, however, there is better value to be had elsewhere. [Jun '13 SSDrivePro]

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]
