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.
For the context of bulk consumer storage (or even SOHO NAS) that’s irrelevant, though, because people are already happily using spinning mechanical 3.5" hard drives for this purpose, and they’re all already SATA. Therefore there’s not logical reason to worry about the physical size or slower write speeds of packing a bunch of flash chips into the same sized enclosure for those particular use cases.
