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]

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]
