Average Bench: 76.2% (496th of 1016)

The 128GB Sandisk Ultra Plus proved to be a bit of a disappointment in comparison to its larger 256GB sibling. The 256GB version has more NAND modules which enable peak sequential write speeds in the region of 450 MB/s. On the 128GB version we saw a peak sequential write speed of just 279 MB/s which is significantly lower than the market leaders which also manage to hit the high 400's. Across the core performance metrics, the 128GB Ultra Plus is around 25% slower than the average of its top competitors and, unlike its 256GB sibling, really struggles to keep up with its direct competition. In terms of value for money the Ultra Plus fares a little better thanks to its reasonably low price tag but there are far better deals to be had in the 128GB category. [Feb '14 SSDrivePro]

It's not slower than evo 840, Sammy's evo 840 is overrated. Like, a lot. Their 120GB is about 2 times slower than their pro models and 15 - 25% slower than 240+ models... SanDisk Ultra Plus 128GB is fast as the 256GB model.
