Our take on the Seagate Exos M ST28000NM003K 28TB HDD

The Seagate Exos M ST28000NM003K is a 28TB enterprise hard drive built on Seagate's heat-assisted magnetic recording platform. It spins at 7200 RPM, uses a 6Gb/s SATA interface with 4Kn or 512e sector formats, and carries a 512MB cache. It is aimed at NAS and server builders who need the highest capacity per bay, and it sits above the 24TB Exos X models in density while staying a conventional 3.5-inch SATA drive. Buyers choose it for capacity per slot; rivals at this tier trade some density for lower power or quieter operation.

Questions and answers

Is the Exos M 28TB worth it over a 24TB drive?
If your array is limited by bay count, the extra 4TB per slot cuts the number of drives and bays you need. If you have spare bays, lower-capacity drives usually give more capacity per dollar.
Does it work in a home NAS?
Yes. It is a standard 3.5-inch SATA drive, so it fits most Synology, QNAP and TrueNAS builds. Check that your NAS lists 28TB drives as supported before buying a full set.
What is the difference between 4Kn and 512e?
Both are sector formats for the same drive. 4Kn uses native 4KB sectors and is preferred by modern systems; 512e emulates 512-byte sectors for older hardware and software.
How loud is it?
It is an enterprise 7200 RPM drive, so expect noticeable seek noise and idle hum. It suits a closet, rack or garage more than a bedroom or living-room setup.
What is in the box?
The drive itself. SATA cables, screws and mounting brackets are not included, so plan for those if your chassis does not supply them.
Does it need special cooling?
Plan for steady airflow across the drive. High-capacity helium-filled drives run warm, and sustained writes benefit from a bay with good ventilation.
