Transcend 820S 480GB M.2 SATA SSD

The Transcend M.2 SSD 820S is an internal solid-state drive specifically engineered for integration into space-constrained systems, including Ultrabooks and thin, light notebooks. Utilizing the M.2 2280 form factor, this 480 GB drive connects via the established SATA III 6Gb/s interface, offering rapid boot times and improved application loading compared to traditional mechanical storage. Sequential data transfer performance is rated up to 530 MB/s for reads and 480 MB/s for writes, suitable for general computing tasks.

The physical design adheres to strict dimensional constraints, measuring only 3.58 mm in height, allowing installation in extremely thin enclosures. This model incorporates 3D NAND flash technology and supports Error Correction Code (ECC) via LDPC coding to ensure data integrity. Furthermore, the drive includes support for Device Sleep (DEVSLP), resulting in an average power consumption of 0.5 W and enhanced thermal management critical for portable devices. Reliability metrics include a robust Mean Time Between Failures (MTBF) of 2,000,000 hours and a total endurance rating of 160 TBW.
