The Crucial MX100 is the first 16nm SSD to date. Aside from NAND, the MX100 shares the same hardware as its more expensive sibling, the M550. Comparing the MX100 and M550 shows that the two drives have similar read speeds but that the MX100 lags by nearly 50% at writing. The newer 16nm NAND reduces costs and accordingly the MX100 is the cheapest SSD (per GB) to date. In terms of performance the MX100 is a compromise which may or may not be worth making depending on individual circumstances. For typical desktop use including email, office documents and web browsing the MX100 is a great choice but power users should look elsewhere. Comparing the 250GB 840 EVO and 256GB MX100 shows that for a marginal premium, the Evo offers better write speeds. (Note: at 500GB they are more evenly matched) [Jun '14 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]
