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]


The Kingston HyperX Fury has the same controller as its HyperX 3K sibling; the only difference between the two drives is the use of cheaper Micron 20nm NAND in the newer Fury. Comparing the performance differences between the HyperX Fury and 3K shows that the newer 20nm NAND results in an effective performance decrease of around 30% for a price saving of just 12%. The Fury was never aimed at the high performance sector of the market but given the known compressible performance weaknesses of its Sandforce 2281 controller and its relatively non-budget price tag, the 120GB Fury will struggle to find rational takers in today's market. There are far better value alternatives available for just a few more dollars. [Sep '14 SSDrivePro]
