Enterprise SAS Drive

The Dell R3H6D is a 1.2TB 2.5-inch SAS hard drive spinning at 10000 RPM. It is built for enterprise storage arrays that demand consistent throughput and hot-swap capability. The bare drive ships without a carrier, so integrators must supply a compatible tray. It suits administrators who need reliable capacity in a compact form factor.

12Gb/s Interface Limits

The SAS interface runs at 12Gb/s, yet the specification also lists a 6Gb/s average latency figure that reflects the physical link negotiation. Throughput will not exceed the controller’s maximum supported speed, and older backplanes may restrict the drive to 6Gb/s operation. Cable length and signal integrity become critical at the higher rate, so passive copper runs must stay within the standard’s reach.

Hot-Swap Installation Notes

Hot-swap trays allow drive replacement without powering down the chassis, but the bare unit requires a carrier that matches the server or enclosure. Misaligned connectors or a missing tray latch are the most common installation faults. Firmware mismatches between the drive and the RAID controller can also prevent the array from recognising the new spindle.

Questions about this item

Is the 1.2TB capacity the only option for this Dell R3H6D drive?

Yes, this model is offered as a single 1.2TB capacity with a 2.5 inch form factor.

What does the 10000 RPM speed deliver in a live server?

The 10000 RPM spindle provides low latency for random read and write workloads typical of enterprise storage arrays.

The headline says 12Gb/s SAS but the spec lists 6Gb/s — which interface speed actually applies?

The drive supports a 12Gb/s SAS transfer rate; the 6Gb/s figure in the specification table refers to average latency.
