The HyperX 3K is an updated version of the regular HyperX, the only difference between the two SSDs is the grade of NAND flash. The regular HyperX's NAND flash is rated at 5,000 erase cycles vs 3,000 on the 3K version so broadly speaking the number of erase cycles before drive failure on the newer drive is approximately 40% less than on the original HyperX. The distinction is largely irrelevant for consumer users because even after 10 years neither of the drives are likely to come even close to their maximum number of erase cycles. As expected both HyperX's have very similar performance profiles which can be seen in this direct comparison of the two drives. Although the HyperX SSDs were strong contenders on release they are showing their age now and can no longer compete amongst the newer drives from Samsung and Plextor which are both cheaper and faster. ^{[Jan '14 SSDrivePro]}

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]}
