Enterprise storage drive

The HGST Ultrastar 7K3000 is a 2TB 3.5-inch internal hard drive built for continuous operation in servers and storage arrays. It spins at 7200 RPM with a 64MB cache and connects through a SAS 6Gb/s interface. The series is rated at 2.0 million hours MTBF and designed for 24x7 accessibility in capacity-optimised workloads.

Suited for RAID and archive workloads

This drive fits administrators who need high-reliability bulk storage for RAID sets, backup targets or near-line archives where sustained throughput matters more than low latency. It is not for buyers who want solid-state speed, silent desktop operation or a consumer SATA model with a shorter duty cycle.

Verify SAS controller and bay compatibility

Check that your host bus adapter or RAID controller supports SAS 6Gb/s and that the chassis provides 3.5-inch drive bays with the correct power and signal connectors. Confirm the system firmware recognises enterprise SAS drives and that your cooling layout can handle continuous 7200 RPM operation.

Questions about this item

Does my motherboard or controller card need a SAS 6Gb/s port to run this 2TB 7200 RPM drive?

Yes, the drive connects through a SAS 6Gb/s interface, so the host must provide a compatible SAS port or a SAS-capable backplane.

Will this 3.5" Ultrastar 7K3000 spin reliably in a chassis that already holds older SATA 3Gb/s drives?

The SAS 6Gb/s interface is backward compatible with 3Gb/s SAS or SATA links, so it will operate alongside earlier drives at the slower link speed.

How can I confirm the 64MB cache and 2.0 million hours MTBF rating are active after installation?

Check the drive identification page in your RAID controller BIOS or SMART utility; it will report the 64MB cache size and the 2.0 million hour MTBF specification.
