Seagate Exos 12 TB 3.5" SATA 128 MB cache internal hard drive

SKU CH-9S0B-K3AXC

Stores 12 TB of data on a 3.5 inch SATA drive with 128 MB cache built for 24 x 7 enterprise workloads

  • 12 TB capacity for massive bulk storage
  • 5 inch form factor fits standard desktop bays
  • 128 MB cache accelerates data transfers
  • SATA 6 Gb/s interface for easy integration
  • 24x7 operation rating for enterprise workloads

Capacity and interface

The Seagate Exos 12 TB 3.5 inch SATA internal hard drive is built for enterprise and data-centre environments that demand high-capacity bulk storage. It targets IT managers and system builders who need reliable 24x7 operation in servers, NAS appliances and archival systems.

Upgrade path

The drive replaces lower-capacity enterprise HDDs when storage density must increase without adding bays. The jump is worth it when workloads exceed the throughput or endurance limits of desktop-class drives and when a five-year limited warranty aligns with procurement cycles.

Sustained workload behaviour

Enhanced caching and TurboBoost technology maintain consistent data-transfer rates during prolonged heavy workloads. Customizable power options help reduce total cost of ownership while advanced write caching minimises the risk of data loss from unexpected power interruptions.

Highlights

  • 12 TB capacity for massive bulk storage
  • 5 inch form factor fits standard desktop bays
  • 128 MB cache accelerates data transfers
  • SATA 6 Gb/s interface for easy integration
  • 24x7 operation rating for enterprise workloads

Questions about this item

Does this 3.5 inch drive fit a standard desktop drive bay?

Yes, the 3.5 inch form factor matches standard desktop drive bays and uses a SATA interface for power and data.

What is the common installation mistake with the SATA connection?

Builders sometimes leave the SATA data or power cable partially unseated, which causes the drive to disappear from the BIOS.

How long is the manufacturer's limited warranty period?

The drive includes a five-year limited product warranty from Seagate.
