Seagate has introduced the Exos M series, a range of enterprise-grade mechanical hard drives available in 30TB and 32TB capacities. The two models, the 30TB CMR ST30000NM004K and the 32TB SMR ST32000NM003K, each offer a minimum of 3TB per disk and use a standard 3.
These drives aren’t for people who care how much they cost, they’re for people who have a server with 16 drive bays and need to double the amount of storage they had in them.
(Enterprise gear is neat: it doesn’t matter what it costs, someone will pay whatever you ask because someone somewhere desperately needs to replace 16tb drives with 32tb ones.)
