Western Digital WD2500BEVS 250GB 5400 RPM 8MB SATA laptop hard drive

Ideal for older laptop upgrades

This 250GB 2.5-inch drive fits standard 9.5mm drive bays and connects via a SATA 1.5Gb/s interface. It suits users replacing a failed drive in a legacy notebook or adding affordable storage to a compatible system. The 5400 RPM spindle speed and 8MB cache deliver adequate performance for everyday office tasks and media playback. Low power draw helps preserve battery life in portable machines.

Simple swap for most 2.5-inch bays

Installation requires only a standard SATA data and power connection inside the laptop chassis. The 9.5mm height matches the majority of notebook drive caddies, though some ultra-thin models use 7mm bays and will not accept this unit. No special drivers are needed; the drive appears in BIOS and the operating system installer automatically. Handle the bare drive by its edges to avoid damaging the exposed circuit board.

Verify bay height and SATA generation

Check that your laptop accepts a 9.5mm tall 2.5-inch drive before ordering, as thinner chassis require a 7mm model. Confirm the system uses a SATA interface rather than an older IDE connector, which this drive does not support. The SATA 1.5Gb/s link will operate at reduced speed on newer SATA 3Gb/s or 6Gb/s controllers but remains fully compatible. Ensure the operating system you plan to install supports drives of this capacity.
