While being priced similarly and performs similarly to competitor SSD. This PCI-E 4.0 SSD is priced little bit lower than other PCI-E 4.0 SSDs. Offering one of the fastest R/W speeds, this SSD pretty much guarantee having to wait only few seconds to transfer most (if not the entire) of your photos, videos, documents or game libraries. Random 4K R/W is slightly lower when compared with Intel 900p/905p but worth it for very fast and new PCI-E 4.0 interface and obviously 1TB of storage. Suggested to pay 10 USD extra for heatsink though. [Oct '19 ColdSpy]

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]
