Capacity and purpose

The Western Digital WD10EADS is a 1TB 3.5-inch desktop hard drive designed for bulk storage in servers and quiet workstations. Its 7200 RPM spindle and 32MB cache suit high-capacity archiving and multimedia libraries rather than low-latency boot duties. Buyers who want faster random access for an operating system should consider a solid-state alternative.

Build and connectors

The bare drive uses a SATA 3.0Gb/s interface and standard 3.5-inch mounting holes, so it fits any desktop bay or hot-swap tray that accepts full-height units. GreenPower technology lowers operating temperature and acoustics, while IntelliPark unloads the heads during idle periods to reduce wear. No screws, cables or mounting brackets are included with the bare drive package.

Compatibility checklist

Verify that your motherboard or controller provides a free SATA 3.0Gb/s port and that the power supply has an available SATA power connector. The drive measures 5.78 inches in length, so confirm the drive cage or bay depth can accommodate it. This unit is sold new; the supplier notes that used examples of this model may show up to 25 bad sectors, but that does not apply to this stock.

Questions about this item

Does the SATA 3.0Gb/s interface limit the 1TB drive in practice?

The SATA 3.0Gb/s link caps the theoretical maximum at 3.0 gigabits per second, so sustained reads and writes from the 7200 RPM platters will not exceed that bandwidth.

What physical space and mounting does the 3.5-inch bare drive need?

It fits a standard 3.5-inch bay measuring up to 5.78 inches long, 4 inches wide and 1 inch high, using the usual bottom or side screw holes.

How is the bare drive installed, and what step is often missed?

Connect the SATA data and power cables, secure the drive with four screws, then initialise and format the 1TB volume in the operating system before use.
