8TB SATA desktop hard drive

The Western Digital WD80EAAZ is an 8TB 3.5-inch internal hard drive built for everyday desktop computing. It spins at 5640 RPM with a 256MB cache and connects via a SATA 6.0Gb/s interface for reliable storage in office and home systems.

Check SATA port and bay space

Verify that your motherboard has a free SATA 6.0Gb/s port and that your case can accommodate a 3.5-inch drive measuring up to 5.79 inches long, 4.00 inches wide and 1.03 inches high. A SATA data cable and a SATA power connector from your power supply are also required for installation.

Suits bulk storage on a desktop PC

This drive suits users who need large-capacity storage for documents, media and backups on a standard desktop. It is not for builders who need the low latency of solid-state storage, for laptops or small-form-factor systems that only accept 2.5-inch drives, or for servers that demand enterprise-class workload ratings.

商品問答

Does the WD80EAAZ come with a SATA data cable and mounting screws, or must they be purchased separately?

The drive is supplied as a bare unit; a SATA 6.0Gb/s data cable and 3.5-inch mounting screws are not included and must be sourced separately.

The WD Blue range lists several capacities — why choose the 8TB 5640 RPM model with 256MB cache?

The 8TB capacity gives the largest single-volume storage in the WD Blue desktop line, while the 5640 RPM spindle and 256MB cache balance throughput and quiet operation for everyday workloads.

What does the 5640 RPM spindle speed mean for actual file transfers and application loading in a desktop PC?

Sequential reads and writes run at typical SATA mechanical-drive rates, so large media files copy steadily, while the 256MB cache smooths small-file access during OS boot and office tasks.
