Our take on the Seagate Exos 28TB 7200RPM SATA 6Gb/s 512e CMR Hard Drive

The Seagate Exos 28TB is an enterprise-class 3.5-inch SATA hard drive built for always-on storage. It uses conventional magnetic recording (CMR) rather than shingled recording, so sustained writes stay predictable, and it is rated for a 550TB-per-year workload with a 2.5 million-hour MTBF. That puts it in the same class as other helium-filled enterprise drives, but with one of the highest capacities you can buy in a single SATA bay. It suits NAS builders, media hoarders and small servers; desktop users who want quiet will find it loud and power-hungry compared with a 5400RPM drive.

What reviewers say

Owners of Exos drives generally report solid reliability in NAS and server use, with sustained speeds close to the rated figures. The recurring complaints are noise and heat rather than failures.

What people mention
  • NoiseCriticisedOwners say seeks are clearly audible and the idle hum carries through a room.
  • ReliabilityPraisedLong-term NAS users report few failures and steady operation around the clock.
  • HeatMixedIt runs warm, so airflow in the case matters more than with low-RPM drives.
  • SpeedPraisedSustained reads and writes come close to the rated 190MB/s.
  • VibrationCriticisedIn dense multi-drive bays, vibration from the 7200RPM motor is noticeable.

Questions and answers

Is this drive CMR or SMR?
It is CMR. Writes stay at full speed instead of slowing during large transfers the way shingled drives can.
Can I use it in a desktop PC?
Yes, it is a standard 3.5-inch SATA drive. It is louder and warmer than a desktop drive, so it suits a case with good airflow.
Is it good for a NAS?
Yes. The 550TB-per-year workload rating and 2.5 million-hour MTBF are meant for always-on arrays. Check your NAS vendor's drive compatibility list first.
How does it compare with a 20TB or 24TB Exos?
Same platform and similar performance, with more capacity per bay. Fewer drives means less power, cabling and noise for the same total storage.
Does it have hardware encryption?
This model does not list self-encrypting drive support. Use software or NAS-level encryption if you need it.
What is in the box?
The drive itself. SATA cables, screws and trays are not included, so plan for your case or NAS caddy.
