Product Identity

The HGST HUA721050KLA330 is a 500GB 3.5-inch internal hard drive that spins at 7200RPM with a 32MB cache. It connects through a SATA 3Gb/s interface and is supplied in new condition for desktop storage upgrades.

Suitability Guidance

This drive suits builders who need a standard SATA hard drive for bulk storage, backups or a secondary data volume in a desktop chassis. It does not suit systems that require a 6Gb/s SATA link, an SSD form factor or a larger capacity than 500GB.

Deciding Specification

The SATA 3Gb/s interface is the single specification that decides compatibility because the motherboard or controller must support this exact link speed for the drive to operate at its rated throughput.

  • 7200 RPM spindle speed delivers responsive data access

Questions about this item

What size drive bay does the 3.5" SATA hard drive need?

It fits a standard 3.5-inch internal drive bay and uses the SATA 3Gb/s interface for power and data.

How do I install the HUA721050KLA330 and what step is often missed?

Mount the drive with four screws, connect the SATA data and power cables, then ensure the BIOS detects the 500GB capacity before formatting.

When will the 7200RPM drive need replacement?

Mechanical drives degrade over time; plan to replace it once SMART tools report reallocated sectors or after several years of continuous operation.
