Seagate Releases 20TB Hard Drives to Answer Mass Data Growth

Data drives today’s most innovative technology and business breakthroughs. Maximizing the value of an organization’s data is dependent on the ability to store, access, and activate as much data as possible.

Today, Seagate Technology Holdings plc, a world leader in mass-data storage infrastructure solutions, launched the new Exos X20 20 TB and IronWolf Pro 20 TB conventional magnetic recording (CMR)-based hard disk drives (HDDs), increasing mass-capacity data storage capabilities.

Seagate Exos X20 for Scalable, Responsive, and Innovative Enterprise Solutions


Seagate’s Exos X20 enterprise HDD is designed for maximum storage capacity and the highest rack-space efficiency. Built with cloud storage in mind, the 20 TB Exos X20 delivers performance for hyperscale data centers and massive scale-out applications.

With low latency of 4.16ms and repeatable response times, Exos X20 provides enhanced caching that performs up to three times better than solutions that only utilize read or write caching. Exos X20 also delivers an increased sustained data rate (SDR) of up to 285 MB/s.

With available Seagate Secure technology and a 2.5M-hr MTBF rating, enterprises count on Exos X20 to realize their greatest data and operational efficiencies, and highest storage densities in the datasphere.

The Exos X20 HDD can be paired with Seagate’s recently announced Exos CORVAULT intelligent storage system to deliver maximum data density in a small footprint. Built on Seagate’s 4U chassis accommodating 106 Exos enterprise drives in only seven inches (18 cm) of rack space, CORVAULT offers over 2.12 PB of SAN-level performance built on Seagate’s breakthrough storage architecture.

Seagate IronWolf Pro 20TB – A High Capacity, Dependable Solutions for Small and Medium Businesses (SMBs)


Seagate’s new IronWolf Pro 20 TB HDD offers network-attached storage (NAS)-optimized AgileArray technology to provide exceptional RAID reliability and compatibility during the heaviest NAS workloads that SMBs might require. Designed with built-in rotational vibration (RV) sensors, IronWolf Pro 20 TB offers RV mitigation to provide reliable performance for NAS systems with little lag or downtime.

Purpose-designed for heavy user workloads, the new IronWolf Pro 20 TB features high reliability with user workload rate limits of 300 TB/year — a necessity for today’s NAS servers. It also offers sustained transfer rates of 285 MB/s giving users the power to collaborate by sharing files, backing up, and tackling heavy workloads in multi-user NAS environments.

The new drive comes equipped with an IronWolf Health Management system for easy access and monitoring drive health, as well as a five-year limited product warranty and three years of Rescue Data Recovery Services for peace of mind.

Pricing and Availability

According to Seagate, both the Exos X20 20TB and the IronWolf Pro 20TB will start shipping this month. But only the IronWolf Pro 20TB is currently available for consumers. The Exos X20 20TB comes with a manufacturer’s suggested retail price of $669.99, while the IronWolf Pro 20TB is slightly cheaper at $649.99.
