Specification Overview

Optimised for NAS Caching

The WD Red SA500 is purpose-built for NAS systems. It caches frequently accessed files to reduce latency. In practice, this speeds up photo rendering and 4K/8K video editing.

Consistent 24/7 Reliability

Unlike standard consumer SSDs, this model is tested for continuous operation. It maintains performance under heavy multi-user loads. So, it fits environments where uptime is critical.

Efficient SATA Performance

With read speeds up to 560 MB/s and write speeds up to 530 MB/s, the drive maximises SATA interface potential. This boosts productivity in home and office setups. However, actual speeds depend on your NAS configuration.

High Random I/O for Databases

The drive delivers 95,000 IOPS random read and 85,000 IOPS random write (4KB). This supports OLTP databases and multi-user access. Also, it improves responsiveness for demanding applications.

Robust Endurance and Thermal Range

The TBW rating is 600. Operating temperature is 0–70 °C, with storage from -55 to 85 °C. The physical dimensions are 69.8 mm width, 100.2 mm depth, 7 mm height, and 37.4 g weight. These specs help confirm fit in your NAS bay.
