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 Kingston HyperX Fury has the same controller as its HyperX 3K sibling; the only difference between the two drives is the use of cheaper Micron 20nm NAND in the newer Fury. Comparing the performance differences between the HyperX Fury and 3K shows that the newer 20nm NAND results in an effective performance decrease of around 30% for a price saving of just 12%. The Fury was never aimed at the high performance sector of the market but given the known compressible performance weaknesses of its Sandforce 2281 controller and its relatively non-budget price tag, the 120GB Fury will struggle to find rational takers in today's market. There are far better value alternatives available for just a few more dollars. [Sep '14 SSDrivePro]
