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 275GB Crucial MX300 supersedes the MX200. Unlike its predecessor, the MX300 is TLC based and therefore suffers from weak write speeds in comparison to MLC drives. The MX300 utilises a sophisticated algorithm to enable fast burst write speeds provided that there is sufficient free space on the disk but as the drive fills up write performance drops to the relatively poor levels seen on other TLC drives (similar to mechanical drives). At current prices (70 USD) the MX300 competes well with other low end drives such as the OCZ Trion, Adata SP550 and Samsung 750 EVO. As stocks build the MX300 is likely to see further price cuts, so it could become a very interesting value proposition. See the current value leaders here[Sep '16 SSDrivePro]
