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]

The 240GB Kingston HyperX Savage sports a Phison PS3110 controller. This marks a welcome departure from Kingston's use of Sandforce 2281 controllers and for the first time in years gives Kinston a shot at competing in the enthusiast/performance segment of the SSD market. Comparing the HyperX Savage and Fury shows that the new Phision controller has an effective speed that is around 40% faster than the Sandforce based Fury. But then comparing the similarly priced OCZ Vertex 460a and Savage shows that, although the overall effective speeds are similar, the Vertex has three times faster 4K Mixed IO speeds. The HyperX Savage is very good for typical consumer use but power users with more demanding I/O loads should probably look elsewhere. [Jun '15 SSDrivePro]
