WD Red SA500 500 GB (WDS500G1R0A)

The WD Red SA500 is a line of SATA SSDs designed for NAS systems, prioritizing continuous operation, caching, durability, and stable 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 for upgrading existing NAS installations or building new systems with various configurations. The line operates through the SATA III 6 Gbps interface and depending on the model offers capacities from 500 GB to 4 TB, with the maximum 4 TB capacity available in the 2.5-inch variant. In terms of speed, the WD Red SA500 delivers sequential read performance up to 560 MB/s and write performance up to 530 MB/s, while random operation performance reaches 95,000 IOPS for reads and 85,000 IOPS for writes. For NAS workloads, endurance specifications are equally important: depending on capacity, durability ranges from 350 to 2500 TBW, and the stated MTTF reaches up to 2 million hours. The WD Red SA500 is built on 3D NAND and optimized for tasks such as OLTP databases, photo processing, 4K/8K editing, and quick access to frequently used files in storage. The WD Red SA500 line operates within a temperature range of 0 to +70 °C, supports 24/7 scenarios, and is ideal for those who need a NAS-oriented SATA SSD rather than a standard consumer drive without consideration for continuous workload.
