WD Red 3.5" 2TB, 5400 RPM, 256MB, SATA III Hard Drive for NAS

This Western Digital WD Red internal hard drive provides 2 TB of storage capacity within a standard 3.5-inch form factor. It is specifically engineered for personal and home office network-attached storage (NAS) systems that contain up to 8 drive bays. Connecting via a SATA 6 Gb/s interface, the drive is built for the demands of continuous, 24/7 operation. Its construction and firmware are optimized to function reliably within always-on, multi-drive environments, handling an official workload rate of up to 180 TB per year.

The drive operates at a spindle speed of 5400 RPM and is equipped with a 256 MB cache to manage data transfers efficiently. This configuration is balanced for the typical read and write patterns found in NAS workloads, prioritizing long-term reliability and consistent access over maximum sequential performance. To help maintain data integrity, the drive incorporates S.M.A.R.T. monitoring technology and includes end-to-end data protection. These features assist in preventing data corruption and provide critical health status updates within the NAS system's management interface.
