Our take on the Seagate Exos M 28TB ST28000NM003K 3.5" SATA HDD

The Seagate Exos M 28TB is an enterprise helium-filled 3.5-inch hard drive with a SATA 6Gb/s interface, 7,200RPM spindle speed, 512MB cache and conventional magnetic recording. Seagate rates it at up to 270MB/s sustained transfer and 2.5 million hours MTBF, backed by a five-year limited warranty. It is built for NAS boxes, servers and cloud data-centre arrays where capacity per bay matters more than speed. Against 20-24TB enterprise drives it packs more room per slot, but it is a spinning disk, so random-access work and boot duties belong on an SSD.

Pros
  • 28TB per drive in a standard 3.5-inch bay
  • CMR recording, so no shingled-write slowdowns in RAID rebuilds
  • Helium-sealed design with 2.5 million hours MTBF
  • 512MB cache and up to 270MB/s sustained transfer
  • Five-year limited warranty
Cons
  • 7200RPM enterprise drive: audible hum and seek noise
  • Needs vibration-aware mounting in multi-drive enclosures
  • Not a boot drive; random I/O is far slower than an SSD
  • High capacity means long rebuild times after a failure

About the Seagate Exos M 28TB ST28000NM003K 3.5" SATA HDD

The Seagate Exos M 28TB ST28000NM003K is a 3.5-inch hard drive for enterprise and cloud data-center storage. It is helium-sealed and uses conventional magnetic recording (CMR). It spins at 7,200RPM and connects over SATA 6Gb/s.

It is designed for always-on enterprise infrastructure, bulk data, backup, archive and large-scale storage pools. PowerChoice and PowerBalance let compatible systems manage idle power and balance watts per terabyte against performance. The drive supports hot-plug operation when the host, controller and operating procedure support it.

The drive has a 2.5 million hour MTBF rating and a 0.35% AFR. Its maximum sustained transfer rate of up to 270MB/s is measured at the outer diameter.

Questions and answers

Is this drive CMR or SMR?
It is CMR (conventional magnetic recording). That matters for RAID arrays, where SMR drives can stall during rebuilds.
Will it work in a home NAS?
Yes, it uses a standard SATA 6Gb/s interface and 3.5-inch form factor. Check that your NAS supports 28TB drives and plan for the noise of a 7,200RPM enterprise unit.
How is it different from a desktop Barracuda?
The Exos M is rated for heavier duty cycles, has a higher MTBF and a five-year warranty. Barracuda drives are aimed at lighter desktop use.
Do I need special mounting?
In multi-drive enclosures, use vibration-dampening trays or screws. Enterprise drives are sensitive to vibration from neighbouring drives.
What is in the box?
The drive itself. SATA cables, screws and mounting brackets are not included, so have those ready for a bare installation.
Where is the Seagate Exos M 28TB ST28000NM003K 3.5" SATA HDD cheapest?
