Thin 7mm laptop drive

The Seagate BarraCuda Pro ST500LM034 is a 2.5-inch internal hard drive built for thin and light laptops and similar small form-factor systems. Its 7mm z-height allows it to fit where thicker drives cannot. The 500GB capacity provides storage for operating systems, applications and personal files. It is suited for users upgrading older notebooks or all-in-one PCs that require a 7mm SATA drive.

7200 RPM spindle speed

The drive spins at 7200 RPM, which is the specification that determines whether it meets the performance needs of a given workload. This rotational speed enables faster data rates up to 160MB/s for snappier file transfers and a more responsive experience. A 128MB cache helps smooth burst operations. Buyers who need the higher throughput of solid-state storage or a different interface will not be served by this drive.

Sustained throughput under load

The manufacturer highlights the highest sustained throughput at 7200 RPM as a core attribute of this model. The 128MB cache and 7200 RPM spindle work together to maintain consistent data delivery during extended read and write sessions. This behaviour supports demanding tasks such as large file moves or continuous recording better than lower-speed alternatives. The drive is backed by a 5-year limited warranty from the manufacturer.

Questions about this item

What does the 7200 RPM speed actually deliver inside a laptop?

The 7200 RPM spindle enables sustained data rates up to 160 MB/s for snappier file transfers and a more responsive experience in thin-and-light systems.

What does the SATA 6.0 Gb/s interface cap at in practice?

The SATA 6.0 Gb/s link supports the drive's maximum sustained throughput of 160 MB/s, so the interface does not bottleneck the 7200 RPM mechanism.

Will the 7 mm height fit my ultra-thin laptop bay?

At 7 mm z-height, 69.85 mm wide and 100.35 mm long, this 2.5-inch drive matches the standard slim bay used in ultrabooks and compact laptops.
