WD Red 3.5" 8TB, 7200 RPM, 256MB, SATA III Hard Drive for NAS

The Western Digital WD80EFAX is an 8 TB internal hard drive engineered for use in Network Attached Storage (NAS) systems. As part of the WD Red product family, it is built for continuous 24/7 operation within multi-drive configurations. This model features a standard 3.5-inch form factor and a SATA 6 Gbit/s interface, ensuring compatibility with a wide range of consumer and small-business NAS enclosures. Its design is optimized to handle the specific workloads associated with data sharing, backup, and streaming in a networked environment.

Performance is delivered through a 7200 RPM spindle speed and a 256 MB cache, which contribute to a sustained data transfer rate of up to 210 MB/s. To ensure consistent operation in multi-bay systems, the drive is equipped with rotational vibration (RV) sensors that help mitigate the effects of vibration from adjacent drives. This model is rated for a workload of 180 TB per year and has a Mean Time Between Failures (MTBF) of 1,000,000 hours, reflecting its design for durability and data integrity under sustained use.
