The 850 Evo SSD Line is Evolving with Samsung's 3D V-NAND


Upgrade virtually every aspect of your computer's performance with Samsung's new 850 EVO, designed with state-of-the-art SSD advancements including 3D V-NAND technology. As the next generation beyond the bestselling 840 EVO, you'll get the 850 EVO's new 3D chip design that enables superior performance, greater reliability and superior energy efficiency so you can work and play faster and longer than ever before.

3D V-NAND Technology


Samsung's innovative 3D V-NAND flash memory architecture breaks through density, performance, and endurance limitations of today's conventional planar NAND architecture. Samsung 3D V-NAND stacks 32 cell layers vertically resulting in higher density and better performance utilizing a smaller footprint.

Incredible Read / Write Speeds


Achieve incredible read/write performance to maximize your everyday computing experience with Samsung's TurboWrite technology. You can obtain up to 1.9x faster performance than the award-winning Samsung 840 EVO. The 850 EVO delivers class-leading performance* in sequential read (540MB/s) and write (520MB/s) speeds. Plus, it gains optimized random performance in all QD for better real-world performance.
*Performance compared to 3-Bit MLC-class SSD drives


Enhanced RAPID Mode


Samsung's Magician software enables RAPID Mode for up to 2x faster performance* by utilizing unused PC memory (DRAM) as a high-speed cache. The newest version of Samsung Magician supports up to a 4GB cache on a system with 16GB of DRAM.
Compared to same drive w/ out RAPID enabled.

Guaranteed Endurance and Reliability


The 850 EVO doubles the endurance* and reliability** compared to the previous generation 840 EVO** and features a class-leading*** 5 year warranty. With enhanced long-term reliability, the 850 EVO assures long term dependable performance of up to 30% longer than the previous generation 840 EVO.
* Measured by Terabytes Written (TBW)
** Measured with Sustained Performance 12hr Random Write Test
*** Highest among 3-Bit MLC-class SSD drives

Improved Energy Efficiency


The 850 EVO delivers significantly longer battery life on your notebook* with a controller designed and optimized for 3D V-NAND that supports Device Sleep for Windows at a highly efficient 2mW. The 850 EVO supports 25% better power efficiency than the previous generation 840 EVO during write operations thanks to ultra-efficient 3D V-NAND only consuming half the energy than that of traditional Planar 2D NAND.
* Compared to standard hard drive & previous generation SSDs

Secure Data Through Advanced AES 256 Encryption


The 850 EVO comes fortified with the latest hardware-based full disk encryption engine. The AES 256-bit hardware encryption secures data without any performance degradation and complies with TCG Opal 2.0. Easily integrate into Windows with Microsoft e-drive IEEE1667 to keep your data protected at all times.

Dynamic Thermal Guard Protection


The 850 EVO's Dynamic Thermal Guard constantly monitors and maintains ideal temperatures for the drive to operate in optimal conditions to ensure the integrity of your data. The Thermal Guard automatically throttles temperatures down when temperatures rise above optimal critical threshold. This protects your data while maintaining responsiveness to help ensure your computer is always safe from overheating.

One-stop Install Navigator Software


In three simple steps, the Samsung One-stop Install Navigator software easily allows you to migrate all the data and applications from your existing drive to the 850 EVO. The included Samsung Magician software also allows you to setup, optimize, and manage your system for peak SSD performance.

End-to-end Integration Solution


Samsung is the only brand to design and manufacture all its components inhouse allowing complete optimized integration. The result – the rock-solid EVO 850, with enhanced performance, lower power consumption with a Samsung Low Power DDR3 SDRAM cache memory and improved energy-efficiency with the MGX controller; all from the #1 memory manufacturer in the world.
