Upgrade to Perfection

          The Samsung 850 PRO SSD redefines storage with the world's first drive based on 3D VNAND flash, offering exceptional read/write performance, reliability, and power management efficiency. The 850 Pro delivers up to 2x the speed, density, and endurance of conventional flash.


          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.

          Enhanced Endurance

          With twice the endurance of the previous model*, the 850 PRO will keep working as long as you do. Samsung's V-NAND technology is built to handle a minimum of 150 Terabytes Written (TBW) over the lifetime of the drive, which equates to a 40 GB daily read/write workload over a 10-year period. Plus, it comes with the industry's top-level 10-year limited warranty.

          Efficient Power Management

          The 850 PRO fully supports Device Sleep mode for Ultrabook™, consuming only 2 milliwats (2mw) of power in its ultra low power state. Plus, its low power DDR2 cache memory provides high performance while consuming up to 30% less power when active and up to 93% less power when idle than typical DDR2 or DDR3 memory.

          Extended Data Security

          Protect your hardware and personal data when you take your notebook on the road with the 850 PRO's Self-Encrypting Drive (SED) technology. The drive includes an AES-256-bit hardware-based, full disk encryption engine that secures your data without the performance loss often experienced with software-based encryption. The 850 PRO’s advanced security complies with the TCG™ Opal v2.0 standard and is compatible with the Microsoft® eDrive IEEE® 1667 protocol. Plus, you can quickly erase data or sanitize your drive with the crypto erase feature.

          Dynamic Thermal Guard Protection

          The 850 PRO includes Dynamic Thermal Guard protection, which sustains performance while minimizing the risk of overheating. This feature monitors and maintains the drive's optimal operating temperature with a throttle feature that automatically drops the SSD's temperature to protect your data while ensuring the responsiveness you expect.
