DELL

DELL ST6000NM0034 6TB 7.2K 12G 3.5" SAS internal hard drive

SKU CH-8EHJ-XF8Z4

6TB 3.5-inch SAS drive with 7200RPM speed and 12Gbps interface for Dell servers

  • 6 TB capacity stores large datasets
  • 7200 RPM spindle speed enables fast data access
  • 12 Gbps SAS interface delivers high throughput
  • 512e sector format improves storage efficiency
  • Hot-swap support simplifies drive replacement

Capacity and interface

The Dell ST6000NM0034 is a 6TB 3.5 inch SAS hard drive spinning at 7200RPM with a 12Gbps interface. It uses 512e formatting and supports hot-swap operation in compatible Dell PowerEdge servers.

Upgrade path

This drive replaces smaller-capacity nearline SAS disks in Dell T-series servers such as the T300, T310, T320, T330 and T410. The jump is worthwhile when current bays are full and additional raw capacity is needed for bulk storage workloads.

Sustained workload behaviour

Under continuous write loads the 7200RPM spindle delivers steady throughput suitable for sequential archiving and backup tasks. The SAS 12Gbps link maintains consistent bandwidth during extended operations without the thermal throttling seen in shorter burst benchmarks.

  • 7200 RPM spindle speed enables fast data access
  • 12 Gbps SAS interface delivers high throughput

Questions about this item

Will the ST6000NM0034 fit in a standard 3.5-inch drive bay?

Yes, the drive uses the 3.5-inch form factor and a SAS 12Gbps interface, matching standard enterprise 3.5-inch hot-swap bays.

How is the drive installed in a Dell T330 server, and what step is often missed?

Slide the drive into an empty hot-swap bay until the carrier clicks, then verify the SAS connector is fully seated; the step often missed is locking the carrier handle to secure the drive.

When should I plan to replace the ST6000NM0034 in a 7200RPM nearline workload?

Monitor SMART reallocated-sector counts and total bytes written; replace the drive when reallocated sectors rise steadily or after the rated workload limit for 7200RPM nearline use is reached.
