Comparing the 150 to the original Vector is disappointing, the newer 150 actually offers marginally worse performance than its predecessor. A strange result but verified (at least partly) by figures on OCZ's own website: 100K 4K read IOPS for the Vector vs 90K 4K read IOPS for the 150. The newer 150 comes with a 5 year warranty which covers 50GB/day vs. the original Vectors 20GB/day but even this should be taken with a pinch of salt considering that the OCZ stock price is currently trading at around seven cents per share, an all time low. Despite the fact that new Vector 150 performs worse than its predecessor it's still a very competent performer and if prices drop, it has the potential to become a decent value proposition. In the meantime however there are far better deals available elsewhere.  [Dec '13 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]
