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 256GB Samsung 850 Pro is the fastest consumer SSD we have seen to date. Thanks to Samsung's new 3D V-NAND the 850 Pro has lower power consumption and better performance, albeit marginally, than both the 840 Evo and 840 Pro. Looking at the benchmark figures for the 840 and 850 Pros shows that the effective performance improvement is 10% whereas the 850 Pro beats the 840 Evo by 16%. These drives effectively saturate SATA 3.0 making it difficult to distinguish between them in day-to-day use. At current prices the 850 Pro is prohibitively expensive, prices need to drop by 15% before it approaches the 840 Pro from a value perspective. Samsung may release a value orientated 850 Evo soon, but for now "most" users are better off with the 840 Pro. [Oct '14 SSDrivePro]
