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.

The 120GB M500 is successor to the phenomenally successful Crucial M4. The M500 was poised to win loyal M4 customers but as it turns out the new M500 is worse for typical consumer use than the now nearly three years old M4. There are some cosmetic performance improvements over the M4 but they are purely synthetic. For example, deep queue speeds are significantly improved and the newer M500 handles mixed IO far better. Consumers require decent sequential read/write speeds which average 435/185 MB/s on the M4 vs 395/134 MB/s on the M500! Other manufacturers have come leaps and bounds over the last three years which has raised the performance bar is several notches. In today's market the new M500 simply cannot compete on performance, it doesn't even come close to the likes of the Samsung Evo or OCZ Vector 150. The M500, however, is one of the cheapest mainstream SSDs available at this time but it's easy to justify spending just a little more for a lot more performance. [Feb '14SSDrivePro]
