Capacity Capacity			240GB			128GB

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 128GB MX100 has the smallest capacity and is the slowest of the MX100 range. Comparing the 128GB and 256GB MX100s shows that the 256GB version has a 75% faster write speed. Within the MX100 range write speeds scale linearly with capacity, as a consequence, the 128GB version struggles to compete with similarly priced drives from other manufacturers. On the other hand, the 512GB version and to a lesser extent the 256GB version offer far better value for money. Overall the MX100 has an effective speed which is amongst the top 30% of 128GB drives so its not bad by any means but there are however both cheaper and faster alternatives available in the now extremely competitive 128GB SSD category. ^{[Oct '14 SSDrivePro]}
