Capacity and interface

This Western Digital RE4 WD2503ABYX is a 250GB 3.5-inch internal hard drive built for desktop systems that use a SATA 3Gb/s connection. It spins at 7200RPM and provides 64MB of cache to serve typical desktop workloads.

Sustained load behaviour

The dual-processor controller and StableTrac technology secure the motor shaft at both ends to reduce vibration during continuous operation. Time-Limited Error Recovery limits error-recovery time so the drive remains responsive in RAID arrays, while Rotary Acceleration Feed Forward and IntelliSeek optimise seek performance under steady demand.

Compatibility checks

Verify that your motherboard or controller offers a free SATA 3Gb/s port and that the chassis has an available 3.5-inch drive bay. Confirm your power supply includes a SATA power connector for the drive. The unit weighs 2.0 pounds, so ensure the mounting location can support that mass.
