The 128GB 840 Pro is a rock solid performer. On release, nearly a year and a half ago, the Pro smashed several speed records. Today, with sequential read/write speeds of 519/438 MBps, the Pro is still one of the fastest SSDs available. One of the Pro's top competitors is Samsungs own, newer 840 Evo. Looking at a raw synthetic speed comparison of the 128GB Pro and Evo is a little misleading. On the face of it the Pro only has a marginal lead over the Evo. This due to the fact that the Evo can only maintain its burst write speed for transfers of up to 3GB, the size of its SLC cache. The Pro on the other hand can sustain higher throughputs indefinitely. The Pro also utilizes MLC which is rated for far more erase cycles than the TLC used in the Evo. Server IO is often continuous and would quickly exhaust the 3GB cache on the Evo but for typical consumer use the Evo will remain within the SLC cache most of the time. [Feb '14 SSDrivePro]

The 120GB Kingston HyperX 3K is nearly two years old, several generations of SSD have passed since its original release. Better 120GB SSDs have more NAND modules than the old HyperX and are able to write faster than the peak 234 Mb/s achieved by the HyperX 3K. The HyperX 3K also has a Sandforce 2281 controller which is unable to write compressed data as well as its more recent competition. All that said the HyperX still has an effective speed of 367 MBps which is respectable and far faster than even the best mechanical drive. With peak 4K read/write speeds of 33/110 MB/s the HyperX 3K also has competent small file performance. To summarize as a current value proposition the HyperX 3K struggles, simply because the likes of Samsung and OCZ have innovated and moved forward in the two years since the HyperX 3K was released. [Feb '14 SSDrivePro]
