WD Red SA500 1 TB (WDS100T1R0B)

WD Red SA500 is a line of SATA SSDs designed for NAS systems, with emphasis on 24/7 operation, caching, durability, and consistent performance in multi-user scenarios. The WD Red SA500 series is available in two form factors: 2.5"/7 mm and M.2 2280, allowing drives to be used both for upgrading existing NAS systems and building new configurations with various layouts. The line operates via SATA III 6 Gbps interface and depending on the model offers capacities from 500 GB to 4 TB, with the maximum 4 TB available in the 2.5-inch variant. In terms of speed, WD Red SA500 delivers sequential read speeds up to 560 MB/s and write speeds up to 530 MB/s, while random operation performance reaches 95,000 IOPS for read and 85,000 IOPS for write. For NAS workloads, endurance specifications are equally important: depending on capacity, durability ranges from 350 to 2500 TBW, with a rated MTTF of up to 2 million hours. WD Red SA500 is built on 3D NAND and optimized for tasks such as OLTP databases, photo editing, 4K/8K video editing, and fast access to frequently used files in storage. The WD Red SA500 line operates in a temperature range from 0 to +70 °C, supports 24/7 scenarios, and is ideal for those seeking a true NAS-oriented SATA SSD rather than a standard consumer drive without consideration for continuous workloads.
