DELL HUH721212AL5200 12TB 7200RPM SAS 256MB 3.5in internal hard drive

SKU CH-V681-QMVYK

A 12TB 3.5in SAS hard drive spinning at 7200RPM with a 256MB buffer for nearline storage

  • 12TB capacity for large-scale data storage
  • 7200RPM spindle speed for responsive nearline performance
  • 12Gbps SAS interface for high-throughput connectivity
  • 256MB cache buffer for improved burst handling
  • Hot-swap 3.5in form factor for tool-less drive replacement

12TB SAS nearline drive for servers

This 12TB 3.5in SAS hard drive spins at 7200RPM with a 256MB buffer and a 12Gbps interface. It is built for nearline storage workloads in Dell EMC arrays and compatible servers that need high-capacity bulk data retention.

Hot-swap tray eases installation

The drive mounts in a standard 3.5in hot-swap carrier so it can be inserted or removed without powering down the chassis. Ensure the backplane and controller both support 12Gbps SAS and 512e sector formatting before slotting the drive in.

Verify controller and backplane compatibility

Confirm your RAID controller or HBA lists 12Gbps SAS and 512e emulation support for 12TB capacities. Check that the enclosure backplane provides the correct SAS power and signal pinout for hot-swap operation.

Questions about this item

How do I verify the 12TB SAS drive is running at 7200RPM after installation?

Check the drive’s reported rotational speed in your RAID controller BIOS or operating-system disk utility; it should show 7200RPM for the HUH721212AL5200.

Does the 0F29535 12TB hot-swap unit ship with a 3.5in carrier or must I buy one separately?

The drive is supplied as a bare 3.5in mechanism; a Dell-compatible hot-swap carrier must be purchased separately if your chassis requires one.

Should I choose the 256MB cache 12Gbps SAS model or a smaller-capacity version for nearline storage?

The HUH721212AL5200 provides 12TB with 256MB cache and 12Gbps SAS; select it when you need maximum nearline capacity in a single bay.
