IronWolf Pro 16TB NAS drive

The Seagate IronWolf Pro ST16000NT001 is a 16TB hard drive built for 24/7 operation in multi-bay NAS enclosures. It targets commercial and enterprise users who need always-accessible storage for RAID arrays, video production workflows or shared network volumes. The drive uses conventional magnetic recording to maintain consistent performance under heavy, sustained workloads.

3.5-inch SATA build

The 3.5-inch form factor fits standard drive bays and connects through a SATA 6.0Gb/s interface. AgileArray firmware adds dual-plane balancing and time-limited error recovery to keep RAID rebuilds smooth in dense chassis. A 256MB cache absorbs burst write traffic while the CMR recording method avoids the latency spikes of shingled media.

7200 RPM thermals and power

Spinning at 7200 RPM, the drive generates typical enterprise-class heat and acoustic output for a high-capacity mechanical unit. Power draw scales with the constant spindle speed and active caching during heavy multi-user access. The design assumes adequate airflow in a server or NAS chassis to sustain reliable long-term operation.

Questions about this item

What transfer speed does the SATA 6.0Gb/s interface actually deliver for the ST16000NT001?

The SATA 6.0Gb/s link caps at 6.0Gb/s, so sustained throughput is limited by the drive's 7200 RPM mechanicals and 256MB cache rather than the bus.

Will the 26.11mm height fit a standard 3.5" drive bay?

Yes, the 26.11mm height matches the standard 3.5" form factor and the 101.85mm by 146.99mm footprint fits any compliant bay.

How do I enable AgileArray for RAID on this IronWolf Pro?

AgileArray is built into the firmware; configure the drive in your NAS RAID controller and the dual-plane balancing with time-limited error recovery activates automatically.
