What is 3D V-NAND and how does it differ from existing technology? Samsung's unique and innovative 3D V-NAND flash memory architecture is a breakthrough in overcoming the density limitations, performance and endurance of today's conventional planar NAND architecture. 3D V-NAND is fabricated by stacking 32 cell layers vertically over one another rather than decreasing the cells dimensions and trying to fit itself onto a fixed horizontal space resulting in higher density and better performance utilizing a smaller footprint. Help maximise daily computing with TurboWrite technology for powerful read/write speeds Help maximise your everyday computing experience with Samsung's TurboWrite technology with powerful read/write performance . It achieves up to 1.9x faster random write speeds for 120/250 GB models compared to the Samsung SSD 840 EVO**. The Samsung SSD 850 EVO delivers great performance in sequential read (540MB/s) and write (520MB/s) speeds. Plus, you also gain great random write performance in QD for client PC usage scenario. *PCmark7 (250GB ) : 6700 (Samsung SSD 840 EVO) > 7600 (Samsung SSD 850 EVO) **Random Write(QD32,120GB) : 36,000 IOPS(Samsung SSD 840 EVO) > 88,000 IOPS(Samsung SSD 850 EVO) Get into the fast lane with the improved RAPID mode Samsung's Magician TM software which provides Rapid Mode for fast processing data speeds* on a system level by utilizing unused PC memory (DRAM) as cache storage. Samsung's newest Magician has increased the maximum memory usage in Rapid mode from 1 GB, in the previous Samsung SSD 840 EVO version, to up to 4 GB with the Samsung SSD 850 EVO when implementing 16 GB of DRAM. The Samsung SSD 850 EVO through minimized performance degradation helps provide sustained performance improvements of up to 30% compared to the Samsung SSD 840 EVO***. *TBW : Total Bytes Written **TBW : 43(Samsung SSD 840 EVO) > 75(Samsung SSD 850 EVO 120/250GB),150(Samsung SSD 850 EVO 500/1TB) ***Sustained Performance(250GB) : 3300 IOPS(Samsung SSD 840 EVO) > 6500 IOPS(Samsung SSD 850 EVO), Performance measured after 12 hours "Random Write" test ^ In addition to a consuer Help secure valuable data through advanced AES 256 encryption The Samsung SSD 850 EVO comes with Samsung's latest hardware-based full disk encryption engine. The AES 256 encryption-bit security technology helps secures data without performance degradation and complies with TCG Opal 2.0. It is also compatible with Microsoft e-drive IEEE1667 to help ensure your data is protected.
