22 TB NAS Hard Drive for Multi-Bay RAID

The Seagate IronWolf Pro ST22000NT001 is a 22TB 3.5-inch internal hard drive built for continuous 24×7 operation in multi-bay NAS enclosures. It uses conventional magnetic recording and a SATA 6.0Gb/s interface to deliver consistent throughput for RAID arrays. The 512MB cache and 7200 RPM spindle speed support heavy multi-user workloads such as video production storage and shared network volumes.

Suited for RAID Arrays.

This drive targets commercial and enterprise NAS deployments that demand high annual workload capacity and rotational vibration tolerance. Its AgileArray firmware and RV sensors are tuned for multi-bay chassis, so it adds little value in single-drive desktop PCs or external enclosures that lack RAID controllers. Buyers needing a low-power laptop drive or a silent single-bay backup disk should consider a different form factor.

550 TB per Year Workload Rating Decides Fit

The 550TB yearly workload rating is the key figure that determines whether this drive matches your environment. Systems that write or rewrite hundreds of terabytes annually — such as surveillance archives, collaborative editing shares or backup targets — fall within this rating. Lighter workloads will not exploit the rating, while heavier sustained write streams may exceed it.

Questions about this item

Will the 22TB SATA 6.0Gb/s drive work in my older four-bay NAS that only supports SATA 3Gb/s?

Yes, the SATA 6.0Gb/s interface is backward compatible with 3Gb/s ports; the drive will run at the slower link speed while keeping its 7200 RPM spindle and 512MB cache.

How do I confirm the IronWolf Health Management system is monitoring the drive after installation?

Install the IronWolf Health Management software on your NAS OS; it will read the drive's SMART data and show prevention, intervention and recovery recommendations on the dashboard.

Does the retail box include mounting screws or a SATA data cable, or must I buy them separately?

Retail or OEM packing may vary; the drive itself is supplied without screws or cables, so budget for standard 3.5in mounting hardware and a SATA data cable if your chassis lacks spares.
