What is V-NAND and how does it differ from existing technology?

Samsung's flash memory is fabricated using an innovative 3D V-NAND architecture, which stacks 32 cell layers on top of one another rather than trying to decrease the cells' length and width to fit today's shrinking form factors. The result is higher density and higher performance using a smaller footprint and a breakthrough in overcoming the density limits of conventional planar NAND architecture.

Boost performance with an industry-leading 3D V-NAND SSD

Boost performance with an industry-leading 3D V-NAND SSD Powered by Samsung's cutting-edge 3D V-NAND technology, the NAND flash memory delivers the ultimate in read and write performance in both sequential and random aspects. This is especially impressive in the 128 GB model* that outperforms similar models on the market by more than 80 MB/s in write speed.

* 850 PRO 128 GB Sequential Write speed: 470 MB/s

Shift into high gear with the enhanced RAPID mode

You can kick up the read / write performance on every capacity when you need it with the RAPID mode. Just like shifting gears in a car, Magician software gives you the option to enhance performance by processing data on a system level using free PC memory (DRAM) as a cache, providing 1.8 times faster performance in the RAPID mode*.

* PCMark Vantage score (512 GB): 53K > 97K(in RAPID mode)

An SSD that won't quit before you do

An SSD that won't quit before you do 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 150 Terabytes Written (TBW) which equates to a 40 GB daily read / write workload over a 10-year period. Plus, it comes with the industry's top-level ten-year limited warranty.

* 840 PRO: 73 TBW > 850 PRO: 150 TBW

An SSD that won†t quit before you do

Work longer with high-efficiency innovation

The efficient, power management components in the 850 PRO enable you work longer and more productively. Boasting the lowest power consumption of any SSD when in full use, the 850 PRO expends less energy while maintaining market-leading performance. The 850 PRO fully supports the sleep mode on the Ultrabook™, consuming only 2 m watts of power. Plus, its LPDDR2 cache memory provides higher performance while consuming 30 percent less power when active and 93 percent less power when idle than typical DDR2 or DDR3 memory.

Work longer with high-efficiency innovation

Safeguard precious data without sacrificing performance

The 850 PRO's SED technology includes an AES-256-bit hardware-based, full disk encryption engine that secures your data without the usual performance degradation and complies with the TCG™ Opal v2.0 standards, protecting PSID, and is compatible with the Microsoft® eDrive IEEE® 1667 protocol.

Safeguard precious data without sacrificing performance

Protect your PC from overheating with Dynamic Thermal Guard protection

The 850 PRO’ss Dynamic Thermal Guard monitors and maintains the drive's optimal operating temperature that automatically drops the SSD's temperature when necessary to protect your data and ensure responsiveness.
