250GB Samsung 860 EVO mSATA Solid State Drive has 3D V-NAND flash memory architecture. It 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 utilising a smaller footprint. Plus, the SSD has up to 550 MB/s read and up to 520 MB/s write for maximum performance.
