Seagate has launched two new hard drives for users who have more data than they know what to do with. Joining the pre-existing Exos and IronWolf Pro families are two new models boasting 20 TB of storage, a relatively massive capacity. These are conventional magnetic recording (CMR)-based drives and not SMR (shingled magnetic recording), the latter of which is usually considered inferior for having generally lower performance.
From Seagate’s press release:
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 20TB 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. […]
Purpose-designed for heavy user workloads, the new IronWolf Pro 20TB features high reliability with user workload rate limits of 300TB/year — a necessity for today’s NAS servers. It also offers sustained transfer rates of 285MB/s giving users the power to collaborate by sharing files, backing up, and tackling heavy workloads in multi-user NAS environments.
Seagate’s Exos X20 20 TB and IronWolf Pro 20 TB will be available beginning this month for $669.99 and $649.99, respectively. The former features a 2.5M-hr MTBF rating.
