Product Description 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, Transcend's SSD220S achieves exceptional transfer speeds of up to 530MB/s read and 480MB/s write. A better choice than HDD Solid-state drives dominate the market for PC upgrades because they are faster and lighter than hard disk drives. SSDs also feature less power, create less noise when in operation, and are more shock-resistant than traditional hard drives. Guaranteed endurance and reliability Transcend's SSD220S offers great Terabytes Written (TBW) values (up to 160 TB) indicating the total amount of data you can write into the drive over its lifetime.
