WD Red SA500 500GB 2.5" SATA SSD

The Western Digital Red SA500 is a 500 GB internal solid-state drive designed specifically for continuous operation within network-attached storage (NAS) systems. Utilizing the SATA III interface, this 2.5-inch drive provides reliable data transfer with sequential rates reaching up to 560 MB/s read and 530 MB/s write. The compact 7 mm height ensures broad physical compatibility with standard NAS enclosures and workstation desktop bays. Its internal architecture relies on 3D TLC NAND flash, optimized for sustained performance necessary in caching and multi-user environments.

This model is rated for superior endurance, featuring a Mean Time Between Failures (MTBF) of 1,750,000 hours and a Total Bytes Written (TBW) rating of 350. These specifications support its function in demanding 24/7 workloads, minimizing latency for applications such as OLTP databases and 4K/8K video workflows. Data integrity is maintained through integrated features like end-to-end data protection and Error Correction Code (ECC) support. Power efficiency is managed via support for DEVSLP, reducing energy consumption when the drive is idle.
