Enterprise 250GB SATA drive

The WD RE WD2503ABYZ is a 250GB 3.5-inch hard drive built for enterprise storage, video surveillance and write-intensive workloads. It runs at 7200 RPM with a 64MB cache on a SATA 6.0Gb/s interface. The bare-drive packaging suits system integrators and server deployments.

Simple SATA installation

Mount the drive in a standard 3.5-inch bay using the 26.10mm height, 101.60mm width and 147.00mm length clearances. Connect one SATA data cable and one SATA power cable. The bare drive ships without screws, cables or mounting brackets, so supply your own hardware. Misaligned screw holes or missing caddies are the common delays.

Check bay depth and controller

Verify the chassis bay accommodates 147.00mm depth and that the backplane or controller supports SATA 6.0Gb/s. Confirm the power supply has a free SATA power connector. RAID or HBA firmware should be current for enterprise workloads. This drive is not suited for portable enclosures or laptop bays.

Klausimai apie šią prekę

How do I confirm the WD2503ABYZ is running at 7200 RPM after installation?

Use a SMART monitoring tool such as CrystalDiskInfo to check the reported rotation rate and verify the drive identifies as a 7200 RPM model.

What comes with the bare-drive WD2503ABYZ and what must I supply?

The package contains only the 3.5-inch drive; you must provide a SATA data cable, a SATA power connector, mounting screws and a 3.5-inch drive bay.

Which capacity of the RE series should I choose for a write-intensive surveillance array?

This model provides 250 GB; select a higher-capacity RE drive if you need more space for continuous recording workloads.
