This listing is for a SanDisk SSD PLUS 480GB 2.5-inch SATA solid state drive, model SDSSDA-480G, built on the SATA III 6 Gb/s interface standard. The drive uses a 7mm 2.5-inch form factor suitable for notebooks, desktops, and SATA-based storage arrays. The SSD PLUS series features multi-level cell (MLC) NAND flash and supports sequential read speeds up to approximately 535 MB/s and sequential write speeds up to around 445 MB/s, depending on host system and workload. It is designed with a shock‑resistant solid-state architecture that eliminates moving parts and supports typical PC workloads such as web browsing, productivity tasks, and standard data access operations. Internal features of the SSD PLUS series include SLC caching for improved burst write performance, compatibility with SATA Revision 3.0 (backward compatible with SATA 1.5 Gb/s and 3 Gb/s), and support for basic monitoring tools such as S.M.A.R.T. attributes via standard system utilities. This specific unit is **faulty** and is **not detected** by its host system. It is therefore offered strictly for parts, repair, diagnostic training, or as donor drive. No accessories, cables, brackets, or software are included. The PCB identifier associated with the drive is 54‑50‑03087.
