Engineered to handle increased workloads, this 4TB drive operates using a SATA III 6 Gb/s interface, a 256MB cache, and a rotational speed of 7200 rpm, which all help to ensure uninterrupted data transfers with a sustained rate of up to 217 MB/s. This drive also features high levels of reliability, with 600,000 load/unload cycles, <10 in 1015 non-recoverable read errors per bits read, dual-plane balance control technology, and 1,000,000 hours MTBF for 8-16 bay NAS systems. Shock protection is provided by a multi-axis shock sensor and WD's NASware 3.0 helps increase system compatibility, allowing Red Pro drives to be more easily integrated with your existing network infrastructure.With advanced firmware technology built into this WD Red Pro drive, NASware 3.0 enables seamless integration, robust data protection and optimal performance for systems operating in the demanding NAS environment. In combination with 3D Active Balance Plus, WD Red Pro also features hardware vibration compensation technology which monitors the drive to correct both linear and rotational vibration in real time, further increasing drive reliability. For overall enhanced accuracy for NAS, WD Red Pro is also equipped with dual actuator technology which improves positional accuracy over the data tracks and head positioning. StableTrac technology then secures the motor shaft at both ends to reduce system-induced vibration and stabilize the drive platters for accurate tracking during read and write operations. Both technologies are important for larger 8 to 16 bay NAS environments.
Built specifically for RAID and NAS environments, WD Red Pro drives come equipped with error recovery controls as part of NASware 3.0, which prevents the drive from fallout in RAID applications. 36.0 dB (Active) 29.0 dB (Idle).
