Samsung's flash memory is fabricated using an innovative 3D V-NAND architecture, which stacks 32 cell layers on top of one another. The result is higher density and higher performance using a smaller footprint and a breakthrough in overcoming the density limits of conventional planar NAND. Powered by Samsung's cutting-edge 3D V-NAND technology, the NAND flash memory delivers class-leading read and write performance for both sequential and random workloads. Using its One-stop Install Navigator software, you can migrate all your data and applications from your SSD or HDD to the 850 PRO quickly and easily.
