Western Digital 6TB Ultrastar DC HC310 7200 RPM 256MB Cache 3.5" SATA internal hard drive HUS726T6TALE6L4

SKU CH-CFXJ-SYVC5

6 TB enterprise-class SATA drive rated for 550 TB yearly workload with 2.5M-hour MTBF and 256 MB cache

  • Enterprise workload rating up to 550 TB per year
  • 5 million hours MTBF for long-term reliability
  • 7200 RPM with 256 MB cache for responsive performance
  • HelioSeal technology for robust operation
  • Rotational Vibration Safeguard protects against vibration

Capacity and workload fit

This 6 TB Ultrastar DC HC310 is built for workloads up to 550 TB per year, roughly ten times the rating of standard desktop drives. It targets servers, NAS appliances and workstations that write heavily every day. Buyers who need only occasional backups or light media storage will not use its endurance headroom.

Thermals, noise and power

The helium-sealed chassis and 7200 RPM spindle keep operating temperatures steady under sustained loads. Rotational Vibration Safeguard technology reduces vibration-induced errors in multi-drive bays, which also lowers acoustic output. The SATA 6 Gb/s interface draws modest power, leaving headroom in typical enclosure power budgets.

Included technologies and their effect

HelioSeal hermetic sealing enables the high areal density while cutting drag and power draw. The 256 MB cache absorbs burst writes and smooths random I/O. A 2.5 million hour MTBF rating and five-year limited warranty reflect the enterprise validation behind the drive. Retail or OEM packaging may vary, but the drive itself is identical.

Questions about this item

How do I install the 3.5" SATA drive and which step is often missed?

Mount the 3.5" drive in a bay, connect the SATA data and power cables, then enable the SATA port in BIOS so the OS can detect the 6TB volume.

What maintenance or replacement will the Ultrastar DC HC310 need later?

No scheduled maintenance is required; the 2.5M hour MTBF rating and 550TB yearly workload limit indicate when the drive should be retired and replaced.

What limit appears first during sustained use of this 7200 RPM drive?

The 550TB per year workload rating is the first ceiling you will reach under continuous heavy write or read cycles.
