PNY's CS900 uses the latest 3D NAND technology that features vertical, stacked expansion of storage cells. By using high-quality flash memory and enhanced firmware algorithms, the CS900 delivers greater performance and reliability. 3D expansion to break through limits Unlike planar NAND memory, 3D NAND flash features memory cells stacked vertically in multiple layers. 3D NAND overcomes density limitations of 2D planar NAND, and delivers a higher level of performance and endurance. Performance boost for everyday computing Taking full advantage of the SATA III 6Gb/s interface and built-in SLC caching technology, PNY's CS900 achieves exceptional transfer speeds of up to 560MB/s read and 520MB/s write. Guaranteed endurance and reliability PNY's CS900 offers great Terabytes Written (TBW) values (up to 2,240 TB) indicating the total amount of data you can write into the drive over its lifetime.
