The WD Red Pro WD221KFGX is a 22 TB internal 3.5-inch hard drive with a SATA (SATA/600) interface. It records data with Conventional Magnetic Recording (CMR). It is designed for NAS systems with up to 24 bays, in 24x7 environments with heavy workloads.
NASware 3.0 firmware is built into the drive. It is meant to improve compatibility, integration, upgradeability and reliability in NAS and RAID systems. The drive also has 3D Active Balance Plus technology and error recovery controls.
A multi-axis shock sensor detects subtle shock events. Dynamic fly height technology adjusts each read-write function to compensate and protect the data. Each drive goes through extended testing for reliable operation.
