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 '14SSDrivePro]
At just 5 months old the Intel 530 Series SSD is the newest SSD in the group test. Unfortunately the 530 uses the same basic formula we have seen going back two and a half years. Sporting a Sandforce 2281 controller coupled with 20nm NAND flash the performance profile struggles with incompressible data and predictably favours reads over writes as with all the other Sandforce 2281 drives we have seen. With peak and average sequential read/write speeds of 498/154 and 454/131 MB/s the 120GB Intel 530 lags the group leaders by 50%. Small file 4K peak and average performance clocked in at 34/101 and 26/76 MB/s which is slightly above average for a leading 120GB SSD. There are faster and cheaper alternatives available in the group test. [Feb '14SSDrivePro]
