Description

The Seagate IronWolf Pro 20TB is a professional-grade NAS hard drive engineered for businesses, creative teams and power users who cannot afford downtime. With a massive 20TB of CMR storage in a standard 3.5-inch SATA form factor, this drive is purpose-built for multi-bay, multi-user NAS environments that run 24×7 — file servers, media production storage, backup targets, virtualisation hosts and shared office storage. If your NAS works around the clock, the Seagate IronWolf Pro 20TB is the drive class Seagate designed for exactly that job.

Why Choose the Seagate IronWolf Pro 20TB?

• True NAS engineering, not a desktop drive: rated for 24×7 operation (8,760 power-on hours per year) in systems with up to 24 bays.
• All-CMR recording: Conventional Magnetic Recording across the whole drive — no SMR slowdowns during RAID rebuilds or sustained writes.
• Helium-sealed design: lower power draw, cooler operation and high platter density for the full 20TB capacity.
• AgileArray firmware: dual-plane balancing and time-limited error recovery deliver best-in-class RAID performance and stop drives being dropped from an array during error recovery.
• Rotational Vibration (RV) sensors: built-in sensors keep performance consistent when many drives spin side by side in one enclosure.
• IronWolf Health Management (IHM): works with leading NAS systems to monitor drive health and recommend prevention, intervention and recovery actions.
• 5-year limited warranty plus 3 years of Rescue Data Recovery Services included.

Performance That Keeps Up With Your Team

A 7200 RPM spindle, 256MB cache and SATA 6Gb/s interface push the Seagate IronWolf Pro 20TB to a maximum sustained transfer rate of 285MB/s — the fastest in its IronWolf Pro generation. In real NAS work that means quicker RAID rebuilds after a drive swap, smoother multi-user file access, faster transfers of large media files for video editors, and backups that finish inside their window instead of spilling into the working day. CMR recording keeps write performance consistent under sustained load — exactly where cheaper SMR desktop drives fall behind. Planning a new storage build? Pair this drive with a dedicated recorder such as the Dahua 32-Channel 4K NVR for surveillance storage, or compare it with the WD Purple 4TB Surveillance Hard Drive for camera-only workloads.

Built for 24×7 Reliability

Businesses trust this line because the Seagate IronWolf Pro 20TB is rated for a 300TB-per-year workload and a 1.2 million-hour MTBF, with an annualised failure rate of just 0.73% at full 24×7 operation. The helium-sealed enclosure runs at an average of only 7.7W during operation and 5.5W at idle, keeping multi-bay systems cooler and cheaper to run — a real consideration when a NAS never switches off. For portable backups alongside your NAS, the Seagate Expansion Portable 2TB External Hard Drive and the Seagate Expansion 1TB Portable are handy companions.

Data Protection: Warranty, Rescue and Health Monitoring

Every Seagate IronWolf Pro 20TB includes a 5-year limited warranty and 3 years of complimentary Rescue Data Recovery Services. If the worst happens — accidental corruption or drive damage — Seagate’s in-house secure labs recover data with an industry-leading 95% success rate, avoiding recovery bills that can cost many times the price of the drive itself. Combined with IronWolf Health Management inside your NAS dashboard, you get early warnings long before a problem becomes data loss. (Rescue services availability varies by country; terms apply.)
