500 GB 2.5" SATA laptop drive

The Seagate BarraCuda ST500LM030 is a 500 GB internal hard drive built for 2.5-inch laptop bays. It spins at 5400 RPM with a 128 MB cache and connects through a SATA 6.0 Gb/s interface. The 7 mm z-height fits slim notebooks and small-form-factor systems.

Suits storage upgrades not speed builds

This drive suits users who need affordable extra capacity for documents, media and backups in a laptop or compact desktop. It is not for buyers who want the low latency or high throughput of solid-state storage. It is also not for systems that only accept 15 mm high drives or that lack a SATA power and data connection.

Check bay height and SATA cables

Before ordering verify that the drive bay accepts a 7 mm high 2.5-inch unit measuring 69.85 mm wide by 100.35 mm long. Confirm the motherboard or caddy provides a standard SATA data port and matching power connector. Ensure the operating system can recognise a 500 GB SATA volume.

Questions about this item

What laptop drive bay height does the 7mm ST500LM030 fit?

The drive measures 7mm high, matching the standard slim 2.5-inch bay found in most modern ultrabooks and thin-and-light notebooks.

Will the SATA 6.0Gb/s interface work with my older SATA 3.0Gb/s motherboard?

Yes, the SATA 6.0Gb/s interface is backward compatible and will operate at the 3.0Gb/s speed supported by the older motherboard.

How can I confirm the 128MB cache and 5400 RPM are active after installation?

Use a tool such as CrystalDiskInfo or the drive properties in Device Manager to verify the reported cache size and rotational speed.
