High-capacity 22 TB enterprise hard drive

The Seagate Exos ST22000NM000C is a 3.5-inch internal hard drive built for enterprise storage workloads. It delivers 22 TB of capacity using conventional magnetic recording at 7200 RPM with a 512 MB cache. The drive connects via a SATA 6.0 Gb/s interface and carries a 2.5 million hour MTBF rating.

Suited for bulk storage arrays.

This drive suits administrators who need maximum terabytes per rack for cloud or scale-out data centres where sequential throughput and capacity density matter. Buyers who need low-latency random access for transactional databases or boot volumes should consider solid-state alternatives. The 26.1 mm height fits standard 3.5-inch bays but will not install in thinner enclosures.

SATA 6.0 Gb/s interface determines host

The single specification that decides fit is the SATA 6.0 Gb/s interface; the drive only works with controllers and backplanes that support this standard. A 4.16 ms average latency and 512 MB cache accompany the interface, but the bus type is the gatekeeper for installation.

Questions about this item

What does the 22TB capacity mean for real-world storage in a server or NAS?

The drive provides 22TB of CMR storage, rated for enterprise workloads with a 2.5M hour MTBF and 512MB cache to sustain large sequential transfers and multi-user access.

How does the SATA 6.0Gb/s interface limit actual throughput?

The SATA 6.0Gb/s link caps burst speed at 6.0Gb/s; sustained read/write will be lower and depends on the 7200 RPM mechanical performance and system controller.

Will the 3.5in form factor with 26.10mm height fit my standard drive bay or hot-swap tray?

The drive measures 147.00mm long, 101.85mm wide and 26.10mm high, matching the standard 3.5in enterprise form factor used in most server chassis and hot-swap carriers.
