Built for multi-bay NAS

The Seagate IronWolf Pro ST14000NT001 is a 14TB 3.5-inch internal hard drive designed for commercial and enterprise NAS systems. It uses conventional magnetic recording and a SATA 6.0Gb/s interface to deliver 24×7 performance in multi-user RAID environments. The 7200 RPM spindle speed and 256MB cache support fast data access for demanding network workloads.

Sustained 24×7 operation

AgileArray technology combines dual-plane balancing with time-limited error recovery to maintain consistent throughput during continuous RAID rebuilds or heavy multi-user traffic. Rotational vibration sensors further stabilise performance across multiple bays. The drive carries a 550TB per year workload rating and a 2.5M hour MTBF, reflecting its engineering for non-stop enterprise duty cycles.

Thermals and power in normal use

The 26.11mm height, 101.85mm width and 146.99mm length fit standard 3.5-inch drive bays while allowing adequate airflow in dense chassis. IronWolf Health Management monitors drive behaviour and provides prevention, intervention and recovery recommendations to keep temperatures and vibration in check. A complimentary three-year Rescue Data Recovery Services plan adds a safety net if unexpected failures occur.

Questions about this item

How much heat and power does the 7200 RPM IronWolf Pro generate during 24×7 operation?

The drive is rated for a 550 TB per year workload and 2.5 million hours MTBF, indicating it is built for continuous multi-bay NAS use with managed rotational vibration.

What host connection and physical bay does the 3.5-inch SATA 6.0Gb/s drive require?

It needs a standard 3.5-inch drive bay with a SATA data cable and a SATA power connector from the system or NAS enclosure.

Will the ST14000NT001 work in an older NAS that only supports drives up to 8 TB?

Compatibility depends on the NAS firmware and controller; the drive uses the standard SATA 6.0Gb/s interface but capacity support must be verified with the enclosure manufacturer.
