WD Red SA500 2 TB (WDS200T1R0B)

The WD Red SA500 is a line of SATA SSDs designed for NAS systems, with emphasis on 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 these drives to be used both for upgrading existing NAS systems and for building new installations with various configurations. The line operates via 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 speeds up to 560 MB/s and write speeds up to 530 MB/s, with random operation performance reaching 95,000 IOPS for reads and 85,000 IOPS for writes. For NAS workloads, endurance metrics are equally important: depending on capacity, durability ranges from 350 to 2,500 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 fast access to frequently used files in storage. The line operates in a temperature range from 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 workloads.
