The Samsung 970 Pro is a third generation NVMe PCIe SSD which replaces the 960 Pro. It comes in a M.2. form factor and features Samsung’s latest Phoenix controller and 64 layer proprietary 3D MLC NAND. MLC NAND has better write consistency but is more expensive than the TLC NAND found in the 970 Evo. The 970 Pro demonstrates a 16% increase in peak sequential write speed over the 960 Pro. There are also improvements in random read and write speeds. Interestingly this iteration of Pro SSDs come with a price cut, with the 512GB retailing at just $250 and the 1TB at $500, whilst at the time of writing, the 512GB 960 Pro is $315. The 970 Pro targets professionals who may rely on Samsung’s 5 year or 600TBW warranty and who may need its extended write performance. But, for most users who rarely transfer more than 22 GB at a time (this is the size of the SLC cache the 500GB 970 Evo), the cheaper 970 Evo may represent better value for money[May '18 SSDrivePro]
