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 BX100 SSD is the value orientated variant of Crucial's M range of SSDs. The BX100 uses the same NAND as its premium MX200 sibling but the BX100 uses a Silicon Motion controller as opposed to the Marvel controller found in the MX range. Feature wise the BX100 is missing SLC caching and there is no hardware encryption (so security frameworks such as windows Bitlocker will operate less efficiently). In terms of I/O performance the BX100 looks promising. Comparing the BX100 and MX100 shows that the newer BX100 may be faster than its predecessor but as yet there are insufficient user benchmarks to draw any definitive conclusions. The BX100 has only just started hitting the shelves so there's plenty of room for price reductions from its already reasonable price tag. I will revisit this review when I have more performance data for the BX100. [Jan '15 SSDrivePro]
