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.
Had good impressions and experiences with Toshiba drives. Chugged along quiet nicely.
Ah I thought I had remembered their hard drive division being aquired but I was wrong! Per Wikipedia:
