Enterprise Capacity and Reliability

The Seagate Exos X22 ST22000NM001E is a 22TB 3.5-inch internal hard drive built for enterprise storage. It runs at 7200 RPM with a SATA 6.0Gb/s interface and a 512MB cache. The helium-sealed design and CMR recording technology support sustained data transfer rates up to 285 MB/s for demanding workloads.

Build Integration Requirements

This drive fits a standard 3.5-inch bay and connects via a SATA data cable and power connector. The 6.0Gb/s interface works with existing SATA controllers and backplanes. Its helium-sealed construction reduces internal turbulence, allowing high capacity without the heat or vibration penalties that can affect dense server chassis.

Helium Sealing and Hot-Plug Benefits

The helium-sealed design lowers drag on the platters, which cuts power draw and acoustic noise while enabling the 22TB capacity in a standard form factor. Hot-plug support lets administrators insert or remove the drive without powering down compatible enclosures, reducing downtime during maintenance or expansion.

Questions about this item

What sustained transfer rate does the 22TB Exos X22 deliver during long sequential workloads?

The drive reaches up to 285 MB/s sustained data transfer, so large backups or analytics scans run at that ceiling for the full capacity.

How much noise and heat does the helium-sealed 3.5" mechanism generate in a server running continuously?

Helium sealing cuts turbulence, letting the 7200 RPM platters run cooler and quieter than air-filled drives of the same speed.

Which host interface and hot-plug capability must my backplane or controller provide for this SATA drive?

A 6.0Gb/s SATA port with hot-plug support is required; the drive uses the standard SATA data and power connectors.
