Designed for high-end computing on client PCs, our 256GB 850 PRO Solid State Drive (SSD) is powered by Samsung's own V-NAND technology which delivers higher density and faster write speed compared with traditional 20nm planar NAND flash. Exceptional Performance with Blazing Fast Read / Write Speeds.Experience a high 100,000 IOPS random read speed and 470MB/s sequential write speed. In addition, RAPID mode allows you to reach optional higher speeds, thanks to Magician software that allows you to enhance performance by processing data on a system level using free PC memory (DRAM) as a cache. Thanks to exceptionally low active power consumption, you can work efficiently for long periods of time. Device Sleep Mode (2mW) is also supported for ultra-thin laptop PCs and high-end desktop mainboards.
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.
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.
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.
Samsung V-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.
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.
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.
The Dynamic Thermal Guard monitors and maintains the drive's optimal operating temperature and automatically drops the SSD temperature in case of overheating.
One-stop Install Navigator software allows you to migrate all the datafrom your SSD or HDD to the 850 PRO easily, using three simple steps.
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.
