Product overview

The Seagate IronWolf Pro 22TB (ST22000NT001) is a NAS-class enterprise drive purpose-built for always-on, multi-bay storage, the drive you put in a Synology, QNAP or TrueNAS array that runs 24/7. It uses conventional magnetic recording (CMR), so it rebuilds and behaves predictably in RAID unlike SMR drives, and it is rated for a 550 TB/yr workload with a 2.5M-hour MTBF and Seagate IronWolf Health Management. At 22TB it is the value sweet spot for high-density NAS; for pure hyperscale data-center duty, the Exos line is the sibling to compare.
