It’s hard to imagine an efficient system without an SSD these days, but in scenarios where disk space is more important than performance, hard drives are still the best option. With this in mind, manufacturers are still pushing the upper limit on hard drive capacity, and Seagate now offers drives with a standard 20TB capacity.

Seagate offers two 20TB hard drives, one from the Exos series and one from the IronWolf series. With the goal of providing customers with “maximum storage capacity and efficient use of rack space”, the Exos X20 20TB drive is the ideal storage solution for data centers. With data rates of up to 285MB/s and response time of 4.16ms, this model is three times better than read/write-only caching solutions. As a data center oriented solution, the Exos X20 is incredibly reliable, delivering an MTBF of 2.5 million hours. Seagate Exos HDDs can be found, among other things, in Exos Corvault storage systems – a 4U chassis with 106 Exos drives, which provides 2.12 petabytes of storage.

Seagate Exos X20 and IronWolf Pro 20TB are new proposals from Seagate in the high-capacity hard drives category. New products offer up to 20 terabytes of data space.

Seagate also unveiled the 20TB IronWolf Pro drive with NAS-enhanced AgileArray technology – a suite of hardware, firmware and software features to improve performance and reliability. The new IronWolf drive has built-in rotational vibration sensors to ensure peak drive performance without causing significant delays or downtime.

With a workload limit of 300TB/year, the IronWolf Pro 20TB is built to handle heavy workloads, while providing transfer speeds of 285MB/s. Compatible with IronWolf Health’s drive access and monitoring management system, this drive is backed by a 5-year warranty and 3-year rescue data recovery service. The Seagate Exos X20 20TB is available for $670, while the IronWolf Pro 20TB is available for $650.
