Frequently Asked Questions

Is the IronWolf 1TB SATA compatible with my NAS?

Yes, the Seagate IronWolf 1TB SATA uses a standard SATA 6Gb/s interface and 3.5" form factor, compatible with any NAS that accepts 3.5" SATA drives. It is widely supported by Synology, QNAP, TrueNAS, and Unraid systems. The 180 TB/year workload rating makes it suitable for always-on NAS environments.

Can I use the IronWolf 1TB SATA in a RAID array?

Yes. The Seagate IronWolf 1TB SATA is designed for RAID deployments. Its 180 TB/year workload rating and 1,000,000 hours MTBF ensure reliability in RAID 5, RAID 6, RAID 10, and ZFS configurations. Enterprise and NAS drives include error recovery features (TLER/ERC) for RAID controller compatibility.

What does the 180 TB/year workload rating mean?

The workload rating indicates the maximum annual data transfer the drive supports while maintaining stated reliability. 180 TB/year means the drive supports approximately 0.5 TB of data transfer per day, suitable for always-on NAS and backup workloads.

How fast is the IronWolf 1TB SATA?

The Seagate IronWolf 1TB SATA spins at 5,400 RPM with a 256 MB cache buffer, delivering sustained transfer rates up to 210 MB/s. This is optimal for sequential workloads like large file transfers and backup operations.

How much power does the IronWolf 1TB SATA consume?

The Seagate IronWolf 1TB SATA draws 5.3W under operating load and 3.4W at idle. For multi-drive configurations, factor these values into your power budget — a 12-drive array would consume approximately 64W under load.
