Our take on the Seagate Exos X24 3.5 Inch Internal Hard Drive 20TB

The Exos X24 is Seagate's enterprise-grade 20TB 3.5-inch hard drive, built for NAS boxes, servers and multi-drive arrays. It spins at 7200 rpm with a 512MB cache and a 2.5 million-hour MTBF rating, and comes in SATA 6Gb/s and SAS 12Gb/s versions. It is a helium-sealed conventional-magnetic-recording drive, so it competes with high-capacity enterprise drives rather than desktop models. Buyers choose it for capacity per bay; it is loud and power-hungry next to a desktop drive, and it is not meant for a single-drive PC.

Pros
  • 20TB per drive cuts the number of bays and cables needed
  • 512MB cache and 7200 rpm suit sustained sequential transfers
  • 2.5 million-hour MTBF and a five-year limited warranty
  • Helium-sealed design keeps power and heat lower than air-filled drives
  • Available in both SATA and SAS versions
Cons
  • Audible seek and spin noise; not suited to a quiet desktop
  • Runs hotter and draws more power than 5400 rpm desktop drives
  • Needs vibration control and staggered spin-up in large arrays
  • No hardware encryption on the standard models
  • Overkill for a single-drive PC or light home use

What reviewers say

Owners of large NAS and server setups generally rate the Exos X24 highly for capacity and steady throughput, and report long service lives. The recurring complaints are noise and heat, plus occasional early failures that require RMA.

What people mention
  • NoiseCriticisedOwners say seek clicks and spin-up are clearly audible, so it suits a closet or rack rather than a living room.
  • CapacityPraisedBuyers value getting 20TB in one 3.5-inch bay, which shrinks the drive count in big arrays.
  • HeatMixedThe helium design helps, but users still report warm temperatures in densely packed NAS units.
  • ReliabilityMixedMany report years of trouble-free 24/7 service, while some had drives fail within the first months.
  • PerformancePraisedSustained sequential reads and writes hold up well for backups and media streaming.

Questions and answers

Is the Exos X24 a good fit for a home NAS?
Yes, if the NAS supports 20TB drives and you can accept the noise. It is built for continuous operation and vibration in multi-drive bays.
SATA or SAS: which version do I need?
Pick SATA for consumer NAS and desktop RAID controllers. Pick SAS only if your server or backplane has a SAS HBA, since SAS drives do not plug into standard SATA ports.
How does it compare with the Exos X22 or X20?
The X24 packs more capacity into the same 3.5-inch format with a larger cache. Speed and reliability ratings are close, so the newer drive mainly buys you more terabytes per bay.
Will it work in a single-drive desktop PC?
It will, but it is loud, warm and costly for that role. A 5400 rpm desktop drive is quieter and better value for a single-drive build.
What is in the box?
The drive itself, with mounting screws in some retail packs. Cables and a bracket are usually not included, so check your case and motherboard accessories.
Does it need special cooling?
Good airflow across the drive is recommended, especially in stacked bays. Keep it within the manufacturer's operating temperature range.
