WD Red SA500 500GB M.2 SATA SSD

This WD Red SA500 solid-state drive (SSD) is an M.2 2280 storage module engineered specifically for deployment within Network Attached Storage (NAS) systems. Its design prioritizes the sustained performance and reliability necessary for continuous, 24/7 operation within multi-user and data-intensive environments. Utilizing the standard SATA 6 Gbit/s interface, the drive offers data transfer speeds appropriate for media serving, frequent backups, and demanding database applications.

The 500 GB capacity model employs 3D NAND flash technology and is optimized to manage the complex read/write cycling typical of an always-on NAS infrastructure. Sequential reading caps at 560 MB/s, while sequential writing reaches 530 MB/s, providing stable throughput under workload. Rated for an endurance of 350 TBW (Terabytes Written) and featuring a two million hour MTBF, this component is structured to meet the longevity requirements of professional NAS installations. The compact M.2 2280 form factor facilitates installation in compatible NAS enclosures or embedded systems where physical space may be constrained.
