Enterprise NAS storage for 24-bay systems

The WD Red Pro WD142KFGX is a 14TB 3.5-inch internal hard drive built for commercial and enterprise NAS enclosures that support up to 24 drive bays. It uses a SATA 6.0Gb/s interface, spins at 7200 RPM and provides a 512MB cache to handle multi-user workloads in RAID-optimised arrays.

Sustained workloads up to 300TB per year

Designed for continuous 24x7 operation, the drive is rated for a 300TB annual workload rate and undergoes extended factory testing for reliable long-term service. NASware 3.0 technology tunes drive parameters for NAS workloads while 3D Active Balance Plus and error recovery controls maintain data integrity during heavy, sustained I/O.

Thermals and power in normal use

The 3.5-inch form factor measures 26.10mm high, 101.60mm wide and 147.00mm long, fitting standard drive bays in multi-bay chassis. Rotation vibration sensors detect and compensate for vibration from neighbouring drives, helping to keep operating temperature and acoustic output stable under typical NAS loads.

Spurningar um þessa vöru

How much power and heat does the 14TB 7200 RPM drive produce during 24x7 operation?

The WD Red Pro 14TB drive is engineered for continuous 24x7 operation in multi-bay NAS enclosures. It supports a 300TB per year workload rate and uses 3D Active Balance Plus technology to minimise vibration and maintain thermal stability across 1 to 24 drive bays.

What host interface and bay count does the SATA 6.0Gb/s drive require to function?

The drive connects via a standard SATA 6.0Gb/s port and fits a 3.5 inch bay. It is validated for NAS systems with 1 to 24 bays and works with RAID-optimised enclosures that provide SATA power and data connections.

Will the 512MB cache SATA drive work reliably in a four-bay NAS alongside older 7200 RPM drives?

Yes. The drive includes Rotation Vibration sensors and NASware 3.0 technology that tune performance for mixed-drive environments. Extended vendor testing ensures compatibility with most multi-bay NAS chassis, allowing it to operate alongside existing drives in a RAID array.
