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 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 utilizing a smaller footprint. Optimize computing with TurboWrite technology for unrivalled read/write speeds Achieve ultimate read/write performance to maximize your everyday computing experience with Samsung’s 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 540MB/s and 520MB/s, respectively. Enjoy optimized random performance in all Queue Depths (QD) for client PC usage scenarios. Increase memory storage with RAPID mode The Samsung 850 EVO M.2 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. Comes with 5 years warranty.
