WD Red Pro 3.5" 6TB, 7200 RPM, 256MB, SATA III Hard Drive for NAS

The Western Digital WD Red Pro is a 6 TB hard disk drive engineered for medium to large-scale multi-bay NAS systems. It is constructed to operate reliably in continuous, 24/7 environments, making it suitable for professional and enterprise applications requiring consistent data availability. The drive's firmware is specifically optimized for the demands of network attached storage, helping to manage performance and data integrity across multi-drive RAID configurations. It is designed to handle the high-intensity workloads found in business storage solutions.

Performance is delivered through a 7200 RPM spindle speed and a 256 MB cache, which facilitates efficient data handling and reduces access latency. The SATA 6 Gbit/s interface provides a standard, high-bandwidth connection for rapid data transfers between the drive and the host system. Integrated Rotational Vibration (RV) sensors detect and counteract disturbances from adjacent drives, maintaining stable performance and reliability in chassis with multiple drives. This technology is critical for preserving data integrity in dense storage arrays.
