16 TB NAS drive for multi-bay enclosures

The Seagate IronWolf ST16000VN001 is a 3.5-inch internal hard drive built for network-attached storage. It spins at 7200 RPM with a 256 MB cache and connects through a SATA 6.0Gb/s interface. AgileArray firmware adds dual-plane balancing and RAID optimisation for multi-bay environments.

Suited for NAS owners who need high capacity

The drive includes rotational vibration sensors to maintain performance when several units operate together. IronWolf Health Management provides prevention, intervention and recovery features. Buyers who need a smaller footprint or a different interface should consider other form factors.

180 TB yearly workload rate defines the endurance

This rating tells you how much data can be written each year without exceeding the design limits. Match your expected annual write volume against that figure to decide if the drive fits the workload.

Questions about this item

Does the ST16000VN001 ship with cables or mounting brackets, or must I buy them separately?

The drive is sold as a bare unit without SATA data cables, power cables or mounting screws; those items must be sourced separately.

How do I decide between the 16TB IronWolf and a smaller capacity in the same series?

Choose the 16TB model when you need the maximum raw space in a single bay and your workload stays within the 180TB per year rating; pick a lower capacity if you want a lower cost per bay or lighter annual write volume.

What does the 7200 RPM rating mean for everyday NAS performance?

The 7200 RPM spindle combined with 256MB cache delivers the sustained throughput needed for multi-user file access and RAID rebuilds in a multi-bay enclosure.
