NAS-optimised 16 TB capacity

The Seagate IronWolf ST16000VN001 is a 16 TB 3.5" internal hard drive built for network-attached storage systems. It targets home and small-business users who need always-on, multi-bay RAID arrays with high annual workload tolerance.

SATA 6.0 Gb/s interface limits

The drive connects through a SATA 6.0 Gb/s link, so maximum throughput is bounded by that bus rather than the 7200 RPM platters or 256 MB cache. Sustained transfer rates will not exceed the interface ceiling, and the 180 TB per year workload rating assumes typical NAS duty cycles within that constraint.

Standard 3.5" bay installation

Mounting uses the industry-standard 3.5" form factor with dimensions of 146.99 mm length, 101.85 mm width and 26.11 mm height. RV sensors compensate for vibration in crowded chassis, while AgileArray firmware handles dual-plane balancing and power management. Installers should verify that the enclosure provides adequate airflow for 24x7 operation.

Questions about this item

Should I pick this 16TB IronWolf or a smaller capacity for my NAS?

Choose 16TB when you need the maximum single-drive capacity in the IronWolf range; smaller capacities use the same 7200 RPM, 256MB cache and SATA 6.0Gb/s specs but give less raw space.

What does the 180TB yearly workload rating mean for daily NAS use?

It is the manufacturer's rated annual data transfer limit for 24x7 operation; staying within it keeps the drive inside its design envelope for continuous multi-bay NAS workloads.

The drive uses SATA 6.0Gb/s — what does that cap in practice?

The SATA 6.0Gb/s interface caps the burst transfer rate at 6.0Gb/s; sustained throughput will be lower and depends on the 7200 RPM mechanical performance.
