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.

Incredible drive, but I fear UserBenchmark is lumping multiple drives into this one. I benchmarked a new-to-market SSD called "Inland Performance Plus 2TB" that sports the new Phison-E18 controller for 7000MBps/6850MBps R/W speeds and it couldn't benchmark it because it "detected a RAM-cached drive". I think this is the previous version with the Phison-E16 controller called "Inland Performance" SSDs. It's confusing because the firmware on the SSD doesn't identify the drive as anything but PCIe SSD, thus the generic name on UserBenchmark, and the lumping together of two unique drives.
