Seagate has launched the Exos X20 20TB enterprise HDD and IronWolf Pro 20TB CMR-based HDDs. Seagate’s Exos X20 is purpose-built for environments like scalable hyperscale applications/cloud data centers and distributed file systems like Hadoop and Ceph, while IronWolf Pro is a NAS-optimized AgileArray drive that combines RAID reliability and compatibility during the heavy 24×7 NAS workloads for SMBs. These new Seagate releases join the recently launched WD Gold and Ultrastar DC HC560 20TB HDDs as the industry’s largest capacity data center drives.

Seagate Exos 20TB
The Seagate Exos X16 and IronWolf Pro were previously available in 16TB and 18TB models, respectively, both of which offered solid performance and an easy way for organizations to scale their NAS devices as their storage needs expand. Seagate has designed the new 20TB Exos X20 model with a focus on cloud storage, as it offers performance for hyperscale data centers and massive scale-out applications.
It also features low latency of 4.16ms, repeatable response times, and enhanced caching. Additionally, Seagate indicates the Exos X20 has an increased sustained data rate of up to 285MB/s and a 2.5M-hr MTBF rating.
