The 250GB Samsung 850 Evo has a similar architecture to its hugely successful predecessor, the 840 Evo. Both drives are TLC based but the 850 uses 3D V-NAND as opposed to regular NAND. Both drives also feature a Turbowrite cache (TWC) which buffers up to 3GB of writes. The TWC enables high burst write speeds but when the cache exhausts write speeds drop to 300 MB/s. Comparing the 850 and 840 Evos shows that effective speed, has improved by 11% and the warranty has been extended from three to five years but prices are also up by 11%. The 850 Evo does put in superb benchmarks (second only to the 850 Pro) but these are only valid within the TWC. At current price levels the 850 Evo struggles to compete with the value leaders[Dec '14 SSDrivePro]

The 250GB Crucial MX200 is successor to the hugely successful MX100. Both drives use the same NAND and controller but the new MX200 features Dynamic Write Acceleration (DWA) which is a new dynamically sized SLC cache. Samsung were the first to introduce SLC caching on the 840 Evo nearly two years ago so Crucial are somewhat late to the party. SLC caches generally only help performance in corner case real word scenarios and benchmarks. I prefer drives without SLC caches because they offer more consistent and sustainable real world IO. Comparing the MX100 and MX200 shows that the newer MX200 has a significantly faster peak write speed which is of course explained by the new DWA cache. Price is the deciding factor between the MX100 and MX200 so although the MX200 isn't priced aggressively yet, it will almost certainly move up the value rankings when retailers build stocks and subsequently cut prices. [Feb '15 SSDrivePro]
