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 OCZ Agility 4 is a relatively old SSD and has been included in the group test as a reference. In terms of overall speed the Agility 4 lags the current ten market leaders by an average of around 30%, considering that the Agility 4 is only 16 months old this highlights just how quickly the SSD market has evolved over the last two years. It's probably not worth upgrading for the sake of more speed unless you have a specific use case that demands it but if you are looking for a speed upgrade, you will gain up to around 50% by going for the Samsung 840 Pro or the OCZ Vector. ^{[Sep '13 SSDrivePro]}
