80 GB SATA/150 desktop drive

The Western Digital WD800JD is an 80 GB 3.5-inch internal hard drive spinning at 7200 RPM with an 8 MB cache. It connects through a SATA/150 interface rated at 150 MB/s and is sold as a bare drive in new condition. The unit targets high-end PCs, workstations and entry-level servers needing modest capacity.

Straightforward SATA installation

Mount the drive in any standard 3.5-inch bay using four screws and attach a single SATA data cable plus a SATA power connector. The SATA/150 interface uses a compact seven-pin cable that removes the alignment issues common with wide parallel ATA ribbons. Hot-swap capability is listed, so the drive can be inserted or removed without powering down the system when the host controller supports it.

Steady throughput for sustained workloads

The 7200 RPM spindle and 8 MB buffer deliver consistent sequential transfer rates up to the SATA/150 ceiling during extended reads or writes. Because the mechanism is designed for desktop and entry-server duty cycles, performance remains stable across long backup jobs or continuous logging tasks rather than peaking only in short bursts. The 150 MB/s interface bandwidth sets the practical ceiling for sustained data movement.

Questions about this item

How can I verify the WD800JD is running at its 7200 RPM spindle speed after installation?

Check the drive’s reported RPM in BIOS or with a SMART monitoring tool; it should show 7200 RPM for the Caviar SE.

What does the bare-drive packaging of the WD800JD include, and what must I provide?

Only the 3.5 inch drive is included; you must supply a SATA data cable, a SATA power connector from your PSU and mounting screws for the drive bay.

Which capacity version of the WD Caviar SE SE WD800JD should I choose for a desktop needing 80 GB storage?

The WD800JD is the single 80 GB model in this series; select it when you need exactly 80 GB of capacity.
