500 GB SATA laptop drive

The HGST 0Y30055 is a 2.5 inch internal hard drive with a 500 GB capacity and a 5400 RPM spindle speed. It connects through a SATA 3.0Gb/s interface and includes an 8 MB cache. The bare drive suits notebook upgrades or external enclosures where a standard height 9.5 mm unit fits.

Simple drop-in installation

The drive uses the common 2.5 inch form factor with SATA data and power connectors, so it slides into most laptop bays or caddies without tools. Ensure the mounting holes align with your chassis and that the SATA cable seats fully; a loose connector is the most frequent cause of the drive not being detected.

Check bay height and interface

Verify that your laptop or enclosure accepts a 9.5 mm tall 2.5 inch drive and provides a SATA 3.0Gb/s port. Systems limited to thinner 7 mm bays or older SATA revisions may not accommodate this unit. Confirm physical clearance and connector compatibility before ordering.

Questions about this item

How can I confirm the 5400 RPM drive is recognised at full 500 GB capacity after installation?

Check BIOS or Disk Management to verify the drive reports 500 GB and a SATA 3.0 Gb/s link speed.

The bare-drive packaging means no screws or cables — what must I source separately?

You will need a 2.5 inch SATA data cable, a SATA power lead and four M3 mounting screws for the 9.5 mm drive bay.

My laptop only accepts 7 mm drives — will the 9.5 mm height of this model fit?

No, the 9.5 mm height exceeds a 7 mm bay; choose a 7 mm drive instead.
