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 3-dimensional chip design that enables superior performance, greater reliability and superior energy efficiency so you can work and play faster and longer than ever before. 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.Achieve incredible read/write performance to maximize your everyday computing experience with Samsung's TurboWrite technology. You can obtain up to 1.9 times faster performance than the award-winning Samsung 840 EVO. The 850 EVO delivers class-leading performance* in sequential read (540MBps) and write (520MBps) speeds. Plus, gain optimized random performance in all QD for better real-world performance.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 amsung Magician supports up to a 4 GB cache on a system with 16 GB of DRAM.he 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 840 EVO during write operations thanks to ultra-efficient 3D V-NAND only consuming half the energy than that of traditional Planar 2D NAND.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.
