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]
