The Evo is remarkable in that, like the Sandisk Extreme II, it features a second level cache. For the 250 GB Evo this consists of a 3 GB Turbowrite cache (TWC) which is a block of high speed Flash Memory. When the TWC is exhausted write speeds drop by approximately 50% but that won't often happen under typical consumer workloads. In terms of raw performance, even with its cache, the Evo still isn't the fastest drive. With a real world speed index reading of 439 MB/s the EVO is however, within reach of the two speed leaders (Vector and 850 Pro). At a price point of $130 the Evo is around 30% cheaper making it the best value for money SSDs I have seen in 2014. Comparing the Evo and the Sandisk Ultra Plus shows that the Evo is the winner but the Sandisk may be a viable alternative thanks to its cache-free, and therefore more consistent performance during extended writes. [Aug '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]
