6 TB SATA Hard Drive

The Western Digital Ultrastar DC HC310 is a 3.5-inch internal hard drive built for enterprise storage workloads. It delivers 6 TB of capacity over a SATA 6.0Gb/s interface at 7200 RPM with a 256 MB cache. Designed for continuous 24x7x365 operation, it carries a workload rating up to 550 TB per year.

Suited For RAID And Server Arrays

This drive fits businesses and system builders who need high endurance in multi-drive environments. Rotational Vibration Safeguard technology helps maintain performance when installed alongside other drives. It is not suited for users who require a 2.5-inch form factor, a different interface, or capacities beyond 6 TB.

550 TB Annual Workload Rating

Questions about this item

Will the SATA 6.0Gb/s interface on this 3.5" drive work with my older motherboard that only has SATA 3.0Gb/s ports?

Yes, the SATA 6.0Gb/s interface is backward compatible with SATA 3.0Gb/s ports; the drive will operate at the lower 3.0Gb/s speed when connected to older controllers.

How can I verify the 7200 RPM spindle speed and 256MB cache are active after installation?

Check the drive details in your operating system's device manager or use a tool like CrystalDiskInfo; both will report the rotational speed and cache size as 7200 RPM and 256MB.

Does the 0B36039 include mounting screws or a SATA data cable, or must I buy them separately?

The drive is supplied as a bare OEM unit; mounting screws and a SATA data cable are not included and must be purchased separately.
