DELL 0JHTD 12TB 7.2K SAS 3.5 internal hard drive

SKU CH-A645-3AZ7G

A 12 TB 7.2K SAS 3.5-inch drive with self-encrypting FIPS security for Dell PowerEdge servers

  • InterfaceSAS
  • Capacity2TB
  • 12 TB capacity for large-scale storage
  • 2 K rpm spindle speed for steady throughput
  • SAS interface for enterprise connectivity
  • 5 inch form factor fits standard drive bays
  • Tested components with updated firmware

Purpose-built for Dell servers

This 12 TB SAS drive is designed for Dell PowerEdge servers and compatible storage enclosures. It targets administrators who need high-capacity nearline storage in a 3.5 inch form factor. The drive uses a 12 Gbps SAS interface and 512e sector formatting for broad compatibility.

Sustained workload behaviour

Rated at 7.2 K RPM, the Ultrastar DC HC520 platform delivers consistent throughput for sequential workloads such as backup, archiving and bulk data ingest. Self-encrypting FIPS-certified firmware helps maintain data integrity during long write sessions without performance penalties.

Thermals noise and power

Enterprise nearline drives of this class are engineered for continuous operation in multi-drive chassis with managed airflow. The helium-sealed design reduces internal friction, helping to keep operating temperatures and acoustic output lower than conventional air-filled equivalents under typical server loads.

What host hardware is required to run this 12Gbps SAS drive?

A 12Gbps SAS HBA or RAID controller with 3.5-inch drive bays, backplane power and signal cables, and a chassis that can cool a 12TB nearline drive.

Will the 12TB SAS drive work in my older PowerEdge R640 or R740?

Yes, the drive is listed as compatible with PowerEdge R640, R740 and many other 14G and 15G servers that accept 3.5-inch 12Gbps SAS drives.
