Enterprise Storage Drive

The HGST Ultrastar 7K6000 0F22798 is a 2TB 3.5-inch internal hard drive built for enterprise workloads. It runs at 7200 RPM with a 128MB cache and connects via a SAS 12Gb/s interface. This bare drive targets data centres, cloud storage clusters and surveillance arrays that demand sustained throughput and proven reliability.

Upgrade From Prior Generation

Compared to the prior 7K4000 generation this series delivers 50% more capacity per drive and 30% better power efficiency in watts per terabyte. Random write performance improves up to three times using media cache technology while sequential read and write speeds rise by 25%. The jump is worth it when density and efficiency gains outweigh the cost of a controller refresh.

SAS Controller Required

Installation requires a compatible SAS 12Gb/s host bus adapter or RAID controller; the drive will not operate on a standard SATA-only motherboard port. The 26.1mm height fits standard 3.5-inch bays but verify chassis clearance for the 147mm length. Common issues include missing SAS cables, unsupported firmware on older controllers and confusion with the SATA variant of the same series.

Points forts

  • 2TB capacity for large-scale storage needs
  • 7200 RPM spindle speed enables fast data access
  • 128MB cache buffer improves response time and data management
  • SAS 12Gb/s interface supports high-performance data centers
  • 2M hours MTBF rating ensures enterprise reliability

Questions sur cet article

Will the 26.1 mm height and 101.6 mm width fit my standard 3.5-inch drive bay?

Yes, the 26.1 mm height and 101.6 mm width match the standard 3.5-inch form factor, so it fits any compliant bay or tray.

Does the SAS 12Gb/s interface plug straight into a SATA controller?

No, SAS 12Gb/s requires a SAS HBA or RAID controller; the drive also supports 6Gb/s SATA but only when attached to a SAS backplane or controller.

How often should I check the 2M hours MTBF rating for replacement planning?

MTBF is a population statistic, not a service interval; monitor SMART attributes and replace the drive if reallocated sectors or pending sectors appear.
