Ultrastar DC HC310 4TB enterprise drive

The Western Digital Ultrastar DC HC310 is a 4TB 3.5-inch internal hard drive built for enterprise storage workloads. It spins at 7200 RPM with a 256MB cache and connects through a SATA 6.0Gb/s interface. Average latency is rated at 4.16ms. The model number is HUS726T4TALE6L4-0B36040.

Check SATA power and bay clearance

Verify that your system has a free 3.5-inch drive bay and a SATA data cable plus a SATA power connector from the power supply. The drive uses the standard SATA 6.0Gb/s interface so the motherboard or controller must support that link speed. Retail or OEM packing may vary and no mounting screws are mentioned in the specifications.

Enterprise thermal and acoustic profile

Designed for continuous operation in enterprise environments, the 7200 RPM spindle and 256MB cache draw typical power for a 3.5-inch drive of this class. Acoustic output is consistent with high-capacity enterprise drives under sustained load. Adequate chassis airflow over the drive is recommended to maintain operating temperatures within specification.
