The Samsung SSD 850 EVO is based on the technologically advanced 3D V-NAND architecture to achieve maximum read and write speeds in sequential and random access. Its layered cell architecture stacks cells vertically instead of side by side.
The result is a higher density and better performance in a smaller footprint, breaking through the limitations of conventional planar NAND architecture. Compared to its 840 EVO predecessor, you now get up to 10% greater flexibility for a better user experience. Having doubled the cell endurance for writing and minimised performance degradation, the 850 EVO assures long-term dependable performance up to 30% longer than the 840 EVO. Samsung has so much confidence in its new SSDs that it now provides a 5-year warranty.
