The Neutron GTX is the faster of the two Neutrons released by Corsair. They both use the same Link A Media LM87800 controller but the GTX features more expensive 24NM Toshiba toggle mode NAND. The main performance gains are seen in the area of sequential writes where the GTX reaches speeds of 482 MB/s vs 359 MB/s on the non GTX version. Unfortunately the impressive boost in sequential write performance is not matched in the area of random 4k read/writes, the GTX's weakest relative areas of performance. The GTX achieved a Real World Performance Index Score of 537.6 MB/s which is approx 60 MB/s faster than the non GTX version, and an impressive score. We consider the GTX version to represent better value for money. That said there are other drives currently on the market that offer better value for money at this time. [Apr '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]
