Seagate Debuts 20TB HDDs for Mass Deployments at Sub-$700 Price

Seagate on Thursday introduced its first 20TB hard drives for mass deployments, just like the company promised several months ago. The new Exos X20 and IronWolf Pro 20TB HDDs target hyperscale datacenters, enterprises, and NAS applications. The new drives will be available later this month for less than $700.

Seagate’s new Exos 20 (18TB and 20TB) and IronWolf Pro 20TB hard drives employ the company’s familiar 5th generation helium-filled platform relying on nine 2.2TB perpendicular magnetic recording (PMR) platters. Those platters are serviced by 18 heads that use two-dimensional magnetic recording (TDMR) technology to deal with a very high track density.
