Capacity and interface

This Western Digital RE3 drive delivers 750GB of storage on a SATA 3.0Gb/s connection. It spins at 7200 RPM with a 32MB cache and fits a standard 3.5-inch bay. The unit is supplied as a bare drive without cables or brackets.

Enterprise workloads versus consumer silence

The RE3 series targets always-on servers, RAID arrays and workstations that prioritise sustained throughput over acoustic comfort. Buyers who need a quiet desktop drive for occasional backups or media playback will find the firmware and vibration profile unsuitable for that environment.

DoD-compliant erase status

Each drive has been erased to the DoD 5220.22 standard and verified functional, though up to 50 bad sectors may be present. The media arrives unformatted and unpartitioned, so the installer must initialise the volume before any data can be written.

Questions sur cet article

Will the SATA 3.0Gb/s interface work with my older SATA 1.5Gb/s motherboard?

Yes, the SATA 3.0Gb/s interface is backward compatible with SATA 1.5Gb/s controllers, so the drive will operate at the slower speed on older motherboards.

How can I verify the 7200 RPM spindle speed is running correctly after installation?

Use SMART monitoring software to check the spindle speed attribute; it should report 7200 RPM during operation.

Does the bare drive include mounting screws or a SATA data cable?

No, the bare drive packaging contains only the 3.5 inch hard drive; mounting screws and SATA data cables must be purchased separately.
