The Kingston HyperX is nearly two years old which in SSD terms is almost an entire lifetime. Starting on a positive note this drive will outperform any mechanical drive hands down, and still has one of the highest sequential read speeds (517 MB/s) we have ever seen on a SATA SSD. That said a balanced performance profile is critical and the HyperX doesn't fare so well against its younger SSD competitors in the other write orientated benchmark categories. The poor results are explained by the Kingston's Sandforce controller which struggles to deliver incompressible data throughput. With a real world speed of 398.1 MB/s and an AS-SSD score of 728 (bottom 28th percentile) there are far better deals to be had at this time. [Apr '13 SSDrivePro]

The 240GB Sandisk Extreme Pro uses the same controller and NAND as its 13 months younger predecessor, the Extreme II. Comparing the Extreme II and Extreme Pro shows that average performance has increased by 10% but peak performance remains broadly unchanged. The Pro features an improved nCache which uses an SLC buffer to cache writes prior to writing them to the slower MLC NAND. In order to benefit from this improved caching, huge amounts of data need to be written for extended periods, an unlikely consumer scenario. Comparing core performance between the Samsung 840 Evo and Extreme Pro shows that the Extreme Pro averages around 12% faster than the Evo. The Extreme Pro also has a 10 year warranty but I wonder if SATA 3 will even be around at that time. Although the Extreme Pro has a superb performance profile it's not a game changer. [Jun '14 SSDrivePro]
