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 Crucial MX100 is the first 16nm SSD to date. Aside from NAND, the MX100 shares the same hardware as its more expensive sibling, the M550. Comparing the MX100 and M550 shows that the two drives have similar read speeds but that the MX100 lags by nearly 50% at writing. The newer 16nm NAND reduces costs and accordingly the MX100 is the cheapest SSD (per GB) to date. In terms of performance the MX100 is a compromise which may or may not be worth making depending on individual circumstances. For typical desktop use including email, office documents and web browsing the MX100 is a great choice but power users should look elsewhere. Comparing the 250GB 840 EVO and 256GB MX100 shows that for a marginal premium, the Evo offers better write speeds. (Note: at 500GB they are more evenly matched) [Jun '14 SSDrivePro]
