Transcend's SATA III 6Gb/s SSD230S 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 SSD230S 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, Transcend's SSD230S achieves exceptional transfer speeds of up to 560MB/s read and 520MB/s write. Guaranteed endurance and reliability Transcend's SSD230S 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. 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. SSD Scope software Transcend SSD Scope is advanced, user-friendly software that makes it easy to ensure your Transcend SSD remains healthy, and continues to run fast and error-free by determining the condition and optimizing the performance of your drive. Guaranteed quality Transcend’s solid state drives are built to the highest standards and rigorously tested, and offer outstanding quality, performance, and reliability.
