WD Red SA500 4TB 2.5" SATA SSD

This Western Digital WD Red SA500 is an internal solid-state drive engineered for performance and endurance within network-attached storage (NAS) ecosystems. Utilizing 3D NAND architecture, the drive is optimized to handle the continuous read and write demands typical of 24x7 multi-user and heavy caching applications. The SSD utilizes the robust SATA 6Gb/s interface standard, ensuring wide compatibility with most modern NAS device bays.

Performance metrics include sequential data transfer rates up to 560 MB/s for reading and 520 MB/s for writing operations. This speed profile supports reduced latency during intensive file access and data synchronization tasks within a controlled network environment. Reliability specifications are substantial, featuring an endurance rating of 2500 TBW and a Mean Time Between Failures (MTBF) of 2 million hours, necessary for long-duration archival and operational longevity. The unit adopts the 2.5-inch form factor with a 7 mm height, fitting common server and appliance bays.
