Enterprise storage drive

The HGST Ultrastar DC HC310 is a 6 TB 3.5 inch hard drive built for enterprise storage arrays. It spins at 7200 RPM with a 256 MB cache and connects through a SATA 6.0 Gb/s interface using 512e sector formatting. The bare drive is supplied without a tray or mounting hardware.

Suited for bulk archives, not speed-critical work

This drive suits administrators who need high-capacity, cost-effective storage for backups, archives or secondary data sets in RAID enclosures. It is not for workloads that demand low latency or sustained throughput beyond what a 7200 RPM SATA mechanism can deliver. Builders needing faster random access should consider solid-state alternatives.

Six terabytes of sequential headroom

The 6 TB capacity comfortably holds large media libraries, surveillance footage or compressed backup sets while leaving room for growth. Sequential reads and writes stay consistent across the platters, but random I/O performance tapers off under heavy concurrent queues. The 256 MB cache absorbs moderate bursts before the mechanical latency of 7200 RPM becomes the bottleneck.

Questions about this item

Does the 3.5 inch form factor need a standard SATA data cable and SATA power connector from my PC?

Yes, the 3.5 inch drive connects with a standard SATA data cable and SATA power connector from the motherboard and power supply.

Will the SATA 6.0Gb/s interface run on an older motherboard that only supports SATA 3Gb/s?

The SATA 6.0Gb/s interface is backward compatible and will operate at SATA 3Gb/s speeds on older motherboards.

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

Use a tool such as CrystalDiskInfo to verify the 256MB cache and 7200 RPM are reported correctly.
