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

The Western Digital WD Red Pro is an 8 TB internal hard drive engineered for medium to large business storage systems with 8 to 16 bays. It is designed to manage high-intensity workloads typical in a multi-user NAS environment. The integrated NASware firmware is optimized for network-attached storage, which enhances system compatibility and operational reliability. This drive provides a robust solution for businesses needing to centralize and protect critical data.

Performance is facilitated by a 7200 RPM spindle speed and a 256 MB cache, which contribute to sustained data transfer rates of up to 267 MB/s. The drive incorporates a multi-axis shock sensor to protect against operational vibration common in NAS enclosures. Additionally, integrated rotational vibration (RV) sensors and dual-actuator technology work to maintain read/write accuracy in multi-drive arrays. These features support the drive's design for continuous 24/7 operation in demanding professional settings.
