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.
