Disclosure: The Ironwolf 16TB NAS HDD is loaned by Seagate

About the Ironwolf 16TB and its functions…

This is the SEAGATE Ironwolf 16TB NAS-specific mechanical drive. This variant provides 14.5TB of usable storage. The earlier reviewed Ironwolf 14TB provides 12.7 TB of storage. This is the highest capacity NAS storage drive that Seagate is providing at the time of writing.

Earlier, I’ve tested the Seagate IRONWOLF 14TB NAS HDD. This is the SEAGATE Ironwolf 16TB NAS drive, a +2TB variant. The housing of the drive is intentionally different from the housing of conventional HDDs as it contains helium. You can read the explanation of it from here.

Ironwolf Specific Features

Typical of the Ironwolf NAS drive series, the SEAGATE IRONWOLF 16TB ST16000VN001 HDD carries 3 years warranty with a spindle speed of 7,200 RPM. These are marketed for Home, SOHO and small business NAS drives, typically up to 8 bays. It comes with a plethora of NAS-specific functions. Its in-house Ironwolf Health Management (IHM) is a 1up from S.M.A.R.T. functions. This emphasis on Prevention, Intervention and Recovery. To use IHM, it needs to work with IHM-enabled NAS units. At the time of writing, it listed ASUSTOR, QNAP, OSAN, Synology, Terra Master and Thecus. There is no support for desktop systems, nor FreeNAS functions- yet.

Apart from the firmware integrations, it does use RV sensors and made to handle vibrations, high workloads in tightly packed 8-bay NAS units. Since NAS units are horizontally stacked with a small/mid-size low profile fan behind it, it is important for these drives to function and tolerate reasonably high temperatures.
