Samsung's 850 PRO SSD features innovative 3D V-NAND architecture which stacks cell layers on top of one another to overcome the density limits of conventional planar NAND. The result is higher performance using a smaller footprint. This SSD delivers the ultimate in read and write performance in both sequential and random aspects. Shift into high gear with the enhanced RAPID mode: process data on a system level using free PC memory (DRAM) as a cache, for performance 1.8 times faster. Thanks to efficient, power management components, work longer and more productively. Other features: AES-256 bit encryption to safeguard data, One-Stop Install Navigator to migrate data to the 850 PRO in three simple steps, and Dynamic Thermal Guard to protect against overheating.
