The 250GB Crucial MX200 is successor to the hugely successful MX100. Both drives use the same NAND and controller but the new MX200 features Dynamic Write Acceleration (DWA) which is a new dynamically sized SLC cache. Samsung were the first to introduce SLC caching on the 840 Evo nearly two years ago so Crucial are somewhat late to the party. SLC caches generally only help performance in corner case real word scenarios and benchmarks. I prefer drives without SLC caches because they offer more consistent and sustainable real world IO. Comparing the MX100 and MX200 shows that the newer MX200 has a significantly faster peak write speed which is of course explained by the new DWA cache. Price is the deciding factor between the MX100 and MX200 so although the MX200 isn't priced aggressively yet, it will almost certainly move up the value rankings when retailers build stocks and subsequently cut prices. [Feb '15 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]
