The 960 Evo SSD is one of Samsung’s premier NVMe SSDs, along with their current flagship, the 960 Pro. The Evo variant is available in a variety of capacities including 250, 500 and 1000 GB, each with a commensurate price tag, whilst the 960 Pro is available in 512, 1024 and 2048 GB capacities. The 960 Evo has lower write endurance compared to the 960 Pro due to its TLC (3-bit) V-NAND flash memory (the 960 Pro consists of MLC (2-bit) V-NAND). As a result, Samsung only guarantee 200 terabytes written on the 512 GB 960 Evo, compared to double that on the 960 Pro, however, this volume of data is very unlikely to affect consumers. The 250 GB 960 Evo has a 13 GB SLC cache which boosts initial write speed to roughly match the 960 Pro but writes exceeding 13 GB drop in speed by over 50%. Overall, the 960 Pro offers more consistent write performance than the 960 Evo, however, this will only impact workloads that exceed the 13 GB. [Nov '17 SSDrivePro]

The 256GB Samsung 850 Pro is the fastest consumer SSD we have seen to date. Thanks to Samsung's new 3D V-NAND the 850 Pro has lower power consumption and better performance, albeit marginally, than both the 840 Evo and 840 Pro. Looking at the benchmark figures for the 840 and 850 Pros shows that the effective performance improvement is 10% whereas the 850 Pro beats the 840 Evo by 16%. These drives effectively saturate SATA 3.0 making it difficult to distinguish between them in day-to-day use. At current prices the 850 Pro is prohibitively expensive, prices need to drop by 15% before it approaches the 840 Pro from a value perspective. Samsung may release a value orientated 850 Evo soon, but for now "most" users are better off with the 840 Pro. [Oct '14 SSDrivePro]
