WD Red Pro 3.5" 12TB, 7200 RPM, 256MB, SATA III Hard Drive for NAS

This WD Red Pro hard drive provides 12 TB of storage in a 3.5-inch form factor, engineered for network-attached storage (NAS) systems. With a spindle speed of 7200 RPM and a 256 MB cache, the drive is configured to handle the data access demands of multi-user environments. It is built for continuous 24/7 operation, making it suitable for always-on NAS applications that require consistent availability. The drive's architecture is specifically intended to function effectively within systems containing one to 24 drive bays.

The drive integrates NASware 3.0 technology, which is designed to improve compatibility and reliability within multi-bay NAS setups. This firmware helps manage heavy workloads and supports RAID configurations by optimizing performance and data protection mechanisms. Sustained read and write speeds of up to 240 MB/s allow for efficient file transfers and data streaming across the network. For proactive maintenance, the drive supports S.M.A.R.T. technology to monitor drive health and report on its operational status.
