The 256GB Samsung 850 Pro is the fastest consumer SSD we have seen to date. Thanks to Samsung's new 3D V-NAND the 850 Pro has lower power consumption and better performance, albeit marginally, than both the 840 Evo and 840 Pro. Looking at the benchmark figures for the 840 and 850 Pros shows that the effective performance improvement is 10% whereas the 850 Pro beats the 840 Evo by 16%. These drives effectively saturate SATA 3.0 making it difficult to distinguish between them in day-to-day use. At current prices the 850 Pro is prohibitively expensive, prices need to drop by 15% before it approaches the 840 Pro from a value perspective. Samsung may release a value orientated 850 Evo soon, but for now "most" users are better off with the 840 Pro. [Oct '14 SSDrivePro]

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]
