ADDLINK S20 3D NAND 512GB 2.5 SATA SATA3 Internal Solid State Drive ( SSD )

The Addlink S20 512GB is a 2.5-inch internal solid state drive built around 3D NAND flash technology. Unlike traditional planar NAND, 3D NAND stacks memory cells vertically in multiple layers, which allows the drive to achieve greater storage density, improved endurance, and more consistent performance over its lifespan. Powered by the SATA III 6Gb/s interface, the S20 512GB reaches sequential read speeds of up to 550MB/s and sequential write speeds of up to 500MB/s, making everyday computing tasks — loading the operating system, launching applications, and transferring files — noticeably faster than a mechanical hard drive. Reliability is reinforced through two built-in firmware technologies: SmartECC and SmartRefresh. SmartECC provides error-correction capabilities that help maintain data integrity over time, while SmartRefresh actively monitors and refreshes stored data to reduce the risk of bit errors during long-term retention. The 2.5-inch, 7mm slim form factor means the S20 fits into a wide range of desktops, laptops, and portable computing devices without requiring a height adapter in most standard bays. Because it contains no moving parts, the drive is inherently resistant to physical shock and vibration — a practical advantage for mobile use. The drive supports backward compatibility with SATA I and SATA II interfaces, so users upgrading older systems can install it without needing new hardware. It is compatible with Windows, Mac OS X, and Linux operating systems. Addlink backs the S20 512GB with a 3-year or 300TBW (terabytes written) warranty, whichever comes first.
