Average Bench: 77.3% (514th of 1058)

Based on 383 user benchmarks.  Models: KINGSTON SH100S3240G, KINGSTON SH100S3

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]

For real world performance, this is currently the best SSD out there. It's not the best benchmark performer nor is it the cheapest but that's because Kingston have rightly focused on real world performance and longevity rather than synthetic benchmark performance.
