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 128GB 840 Pro is a rock solid performer. On release, nearly a year and a half ago, the Pro smashed several speed records. Today, with sequential read/write speeds of 519/438 MBps, the Pro is still one of the fastest SSDs available. One of the Pro's top competitors is Samsungs own, newer 840 Evo. Looking at a raw synthetic speed comparison of the 128GB Pro and Evo is a little misleading. On the face of it the Pro only has a marginal lead over the Evo. This due to the fact that the Evo can only maintain its burst write speed for transfers of up to 3GB, the size of its SLC cache. The Pro on the other hand can sustain higher throughputs indefinitely. The Pro also utilizes MLC which is rated for far more erase cycles than the TLC used in the Evo. Server IO is often continuous and would quickly exhaust the 3GB cache on the Evo but for typical consumer use the Evo will remain within the SLC cache most of the time. [Feb '14 SSDrivePro]
