12 TB SATA desktop drive

The Western Digital WD120EAGZ is a 12 TB 3.5-inch internal hard drive that spins at 7200 RPM and carries a 512 MB cache. It connects through a SATA 6.0 Gb/s interface and uses CMR recording technology for consistent write performance.

Built for bulk storage on a desktop

This drive suits users who need large, affordable capacity for documents, media libraries or backups on a standard desktop PC. It is not intended for laptops, small-form-factor systems or any device that cannot accommodate a 3.5-inch bay with 26.10 mm height clearance.

Steady throughput under sustained writes

The 7200 RPM spindle and generous cache keep sequential transfer rates stable during long copy jobs or continuous recording workloads. Acoustic output and vibration remain at typical desktop levels even when the drive runs for extended periods.

商品問答

What type of SATA port and power connector does the WD120EAGZ require?

The drive connects to a standard SATA 6.0Gb/s port and uses a regular 15-pin SATA power connector from your power supply.

Will the 7200 RPM speed and 512MB cache of this 12TB drive work with an older motherboard limited to SATA 3.0Gb/s?

Yes, the SATA 6.0Gb/s interface is backwards compatible; the drive will run at the older bus speed while keeping its 7200 RPM spindle and 512MB cache.

How can I verify the WD120EAGZ is healthy and performing at 7200 RPM after installation?

Check SMART attributes for zero reallocated sectors and use a benchmark tool to confirm sustained transfer rates consistent with a 7200 RPM CMR drive.
