20 TB host-managed SMR drive

The Seagate Exos X20z ST20000NM001J is a 20 TB 3.5-inch internal hard drive spinning at 7200 RPM on a SATA 6.0 Gb/s interface. It uses host-managed shingled magnetic recording with a 256 MB cache and is built for continuous 24/7 operation in enterprise environments.

Suited for sequential write workloads

This drive fits data centres and bulk-storage arrays that can manage SMR zones directly in software. It is not for general desktop use, boot drives or random-access databases that need conventional magnetic recording. Builders without host-aware file systems or object-store layers should look elsewhere.

Standard 3.5-inch SATA installation

The drive mounts in any 3.5-inch bay with standard SATA data and power cables. No special drivers are required, but the host must implement zone management for the SMR layout; treating it as a regular block device will cause severe write stalls and premature wear. Zone-aware software is the only common pitfall.

Frågor om den här produkten

What host software or controller is required to manage the SMR zones on this Exos X20z drive?

The ST20000NM001J uses Host-Managed SMR technology, so the operating system or application must implement the ZBC/ZAC command set to control the sequential write zones.

Will this 20TB SMR drive work in a standard RAID controller that expects conventional drives?

Most hardware RAID controllers treat the drive as a normal block device and cannot issue the zone commands that Host-Managed SMR requires, so performance will degrade or the array may fail.

How can I verify the drive is correctly handling sequential write zones after installation?

Use a zone-aware tool such as libzbc or smartctl to report the zone type and write-pointer position; sequential zones should show an advancing write pointer after each write.
