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 240GB Sandisk Extreme Pro uses the same controller and NAND as its 13 months younger predecessor, the Extreme II. Comparing the Extreme II and Extreme Pro shows that average performance has increased by 10% but peak performance remains broadly unchanged. The Pro features an improved nCache which uses an SLC buffer to cache writes prior to writing them to the slower MLC NAND. In order to benefit from this improved caching, huge amounts of data need to be written for extended periods, an unlikely consumer scenario. Comparing core performance between the Samsung 840 Evo and Extreme Pro shows that the Extreme Pro averages around 12% faster than the Evo. The Extreme Pro also has a 10 year warranty but I wonder if SATA 3 will even be around at that time. Although the Extreme Pro has a superb performance profile it's not a game changer. [Jun '14 SSDrivePro]
