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]


The Sandisk Ultra II sits above Sandisk's Ultra Plus and below their Extreme Pro. The Ultra Plus would probably have been phased out completely were it not for its continued success within budget space. The Ultra II is the first Sandisk drive to utilize cheaper (and slower) TLC NAND. Similarly to the Extreme Pro, the Ultra II utilizes an nCache which operates a portion of the NAND in simulated SLC mode. This strategy also matches the one employed by Samsung's now 14 months old Evo. Comparing the Ultra II and Evo shows broad performance equivalence which given the Ultra II's 15% price discount makes it the better choice today. That said it's probably worth waiting for the release of the 850 Evo which will pack another 14 months of Samsung's market leading R&D and will probably steal the show. [Sep '14 SSDrivePro]
