Average Bench: 88.2% (249th of 980)

Based on 1,277 user benchmarks.  Models: SanDisk SDSSDXP240G, SanDisk SDSSDXP2

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]

I have had 4 separate units of this model fail 5 times in 3 months. There is no use for this type of unreliable SSD. Lost data, time and money.

Very good
