Enterprise-Grade 2TB Nearline Drive

The HGST Ultrastar 7K3000 HUA723020ALA640 is a 3.5-inch internal hard drive built for enterprise storage environments. It delivers 2TB capacity at 7200 RPM with a 64MB cache over a SATA 6.0Gb/s interface. The drive carries a 2.0 million hour MTBF rating and uses a fifth-generation five-platter mechanical design. It includes Data Lifeguard and Shock Guard features along with encryption support.

Suited for High-Capacity Server Arrays

This drive fits nearline workloads that demand sustained throughput and proven reliability in multi-drive enclosures. Buyers needing low-latency random access for transactional databases or boot volumes should look at solid-state alternatives. Systems requiring a smaller 2.5-inch form factor or a different interface protocol cannot use this unit. It is not intended for portable or external enclosures without a compatible carrier.

Integrates into Standard 3.5-Inch Bays

The SATA 6.0Gb/s connection plugs directly into any compatible backplane or motherboard port without adapters. Its enterprise-grade mechanical design reduces vibration sensitivity in dense chassis, freeing administrators from frequent drive swaps. The bare-drive packaging means mounting screws and caddies must be sourced separately for the target server or storage array.

Questions about this item

Does this 3.5-inch SATA 6.0Gb/s drive need a 3.5-inch drive bay and a SATA data plus power cable to operate?

Yes, the 3.5-inch form factor requires a standard 3.5-inch bay and both a SATA data cable and a SATA power connector from the power supply.

Will the 64MB cache and 7200 RPM speed benefit a system that still uses a SATA 3.0Gb/s controller?

The drive negotiates down to 3.0Gb/s automatically, so the larger cache and 7200 RPM rotation still improve burst and sustained transfers compared with smaller, slower drives on the same port.

How can I verify the 2TB capacity and 2.0 million-hour MTBF rating after installation?

Check the reported capacity in the OS disk utility and run the manufacturer’s diagnostic tool; it will confirm the 2000GB size and report the drive’s health against the 2.0M-hour MTBF spec.
