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 275GB Crucial MX300 supersedes the MX200. Unlike its predecessor, the MX300 is TLC based and therefore suffers from weak write speeds in comparison to MLC drives. The MX300 utilises a sophisticated algorithm to enable fast burst write speeds provided that there is sufficient free space on the disk but as the drive fills up write performance drops to the relatively poor levels seen on other TLC drives (similar to mechanical drives). At current prices (70 USD) the MX300 competes well with other low end drives such as the OCZ Trion, Adata SP550 and Samsung 750 EVO. As stocks build the MX300 is likely to see further price cuts, so it could become a very interesting value proposition. See the current value leaders here[Sep '16 SSDrivePro]
