The 850 Pro is Samsung's new flagship consumer SSD, and the follow-up to
the wildly popular 840 Pro, which was one of the best performing SSDs
money could buy . The Samsung SSD 850 Pro is a standard internal drive that supports the
latest SATA 3 (6Gbps) standard and will work in any instance where a
regular SATA hard drive is used. It is 7 mm thick . The MEX controller has received a 100MHz speed bump, to 400MHz, but the
headline new feature is 3D V-NAND flash memory, Samsung's proprietary
3D technology, where the memory chips are layered vertically, as well as
horizontally.
As flash memory cells get smaller, SSD makers are encountering the same problems the semiconductor industry is facing. The cells are now tiny, down to the size of 1nm, and at this scale the laws of physics mean charge easily leaks between them, requiring new materials and insulation techniques to allow for continued improvements in performance and capacity. A 3D arrangement mitigates some of these problems.The 850 Pro represents the second generation of 3D V-NAND, as it debuted in enterprise SSDs, with 24 cells layered on top of each other. This time, Samsung has managed to layer 32 flash cells together.
The 850 Pro allows you to manage all of its features via the Samsung Magician software, which is currently only available for Windows., you can use the software to turn on or off encryption, over-provisioning and Rapid mode.
Samsung claims that the 512GB 850 Pro can deliver 550MB/s sequential read speeds and 520MB/s sequential write speeds. In its documentation, the company further claims 100,000 IOPS during random 4K reads and 90,000 IOPS during writes.
It comes with Samsung Magician software It performs multiple functions, offering common SSD maintenance tasks such as firmware updating and secure erase, which wipes your personal data and restores performance to (near) factory levels. At a glance, the software will also tell you the health of your drive, the amount of storage being used and the amount of data that has been written to it, with full SMART diagnostic data just a click away. There's also a benchmarking tool.
