850 PRO


Samsung V-NAND technology

Samsung V-NAND technology enables SSD manufacturing in higher density and higher performance and a breakthrough in overcoming the density limits of conventional planar NAND architecture.

World’s first 2 TB SSD

Samsung ushers in a new era of terabyte capacity with the world’s first 2 TB SSD for client PCs. Powered by V-NAND, the SSD 850 PRO 2 TB allows you to store more programs and data onto a single spacious SSD, resulting in greater PC performance.

Boost your PC performance

Powered by V-NAND technology, the 850 PRO delivers the ultimate in read and write performance in both sequential and random aspects, with sequential read speeds up to 550 MB/s and random read speeds up to 100,000 IOPS.

Enhanced 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)

Unmatched endurance

SamsungV-NAND technology is built to handle 300 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 10-year limited warranty. * 850 PRO 128/256 GB: 150 TBW, 512 GB/1 TB/2 TB: 300 TBW

Work longer with
high power efficiency

The 850 PRO expends less energy while maintaining market-leading performance. The 850 PRO supports the sleep mode on the Ultrabook™, consuming only 2mW of power.

Safeguard precious data

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

Protect your PC from overheating

The Dynamic Thermal Guard monitors and maintains the drive's optimal operating temperature and automatically drops the SSD temperature in case of overheating.

Migrate data without hassle

One-stop Install Navigator software allows you to migrate all the data from your SSD or HDD to the 850 PRO easily, using three simple steps.

Ensure each component
works seamlessly

Samsung designs all SSD components in house, allowing complete optimization.
The result – enhanced performance and lower power consumption with Low Power DDR2
DRAM cache memory and energy-efficiency controller.
