Samsungs unique and innovative 3D V-NAND flash memory architecture is a breakthrough in overcoming the density limitations, performance and endurance of todays conventional planar V-NAND architecture. 3D V-NAND stacks 32 cell layers vertically over one another rather than decreasing cell dimensions and trying to fit itself onto a fixed horizontal space. As a result, the technology provides higher density and better performance utilising a smaller footprint. Achieve ultimate read / write performance to maximise your everyday computing experience with Samsungs TurboWrite technology. Compared to the 840 EVO, the 850 EVO shows an increased overall user experience of approximately 13%, partly thanks to the now 2x faster random write speeds. The 850 EVO delivers top-notch performance in its class, with sequential read and write speeds of 540 MB/s and 520 MB/s, respectively. Enjoy optimised random performance in all Queue Depths (QD) for client PC usage scenarios. The Samsung 850 EVO mSATA is a speed machine. With the latest Samsung Magician software, you can activate the RAPID mode to tap unused PC memory (DRAM) and use it as cache storage up to 25% of the total DRAM capacity. With the dramatic increase in storage, data processing speeds and random QD can be up to 2x faster under the RAPID mode. The 850 EVO delivers guaranteed endurance and reliability by doubling the Total Bytes Written (TBW) compared to the previous generation of 840 EVO along with an industry-leading 5 year warranty. Through improving performance by up to 30%, the 850 EVO allows sustained performance making it one of the most dependable storage solutions. The 850 Evo introduced the 2 mW device sleep mode feature in the 840 EVO, and now the 850 EVO is introducing cutting-edge 3D V-NAND Technology (which consumes 50% less energy than Planar 2D V-NAND), giving you 25% more power efficiency during write operations. The versatile 850 EVO mSATA has you covered no matter which connector type or physical slot size your device supports, making it perfect for todays desktops, laptops, and especially ultra-thin space-constrained tablet PCs. The 850 EVO comes fortified with the latest hardware-based full disk encryption engine. The AES 256-bit encryption and TCG Opal 2.0 encryption secure data without any performance degradation. It is also compatible with IEEE-1667 for Microsofts eDrive so that your data is protected at all times for your peace of mind. The 850 EVO Dynamic Thermal Guard feature constantly and automatically monitors and maintains the ideal temperature for the drive to operate optimally. With the One-Stop Install Navigator, Samsung Data Migration and Magician software are installed simultaneously for your convenience to ensure that your SSDs settings are optimised for efficient data transfer. As the industry SSD leader, Samsung is uniquely positioned to design, develop and manufacturer exclusively in house, resulting in a seamlessly integrated and fully optimised solution for enhanced performance and eliminating the risk of component compatibility errors.
