At four months old, the 128GB Toshiba Q Series Pro is the newest SSD in the group test. It's always nice to see new drives pushing established speed boundaries and the Q Series Pro does exactly that. With peak and average sequential read/write speeds of 521/481 and 422/333 MB/s the Q Series Pro beats the 128GB group average peak write speed by 45% and is bested only by the Samsung Evo. A particularly impressive aspect of the Q Series Pro's performance profile is its mixed IO performance where it beats the average of the group leaders by a stunning 50% and sets new sequential/4k mixed IO records of 502/40.4 MB/s. The ability to handle concurrent read and write operations well means that the Q Series Pro will rarely pause for breath, even when faced with varying IO demands, a great server orientated trait. Overall the Q Series Pro has a very robust performance profile and is well priced making it one of the top 128GB SSDs of 2014. [Feb '14 SSDrivePro]

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]
