Purpose-built laptop storage

The Seagate ST1000LM035 is a 1TB 2.5-inch internal hard drive built for notebooks that accept a 7mm SATA device. It spins at 5400 RPM with a 128MB cache and a 6.0Gb/s SATA interface, delivering 1TB of mechanical storage in a thin, light package.

Ideal for capacity-focused upgrades

This drive suits owners of compatible laptops or external enclosures who need maximum terabytes per millimetre at low cost. It is not for users who require the low latency and high throughput of solid-state storage, nor for systems limited to thinner 5mm bays or proprietary connectors.

Drop-in SATA integration

The standard SATA 6.0Gb/s interface allows direct replacement of an existing 2.5-inch drive without adapters or firmware changes. Its 7mm height and light weight free up space and mass budget in slim chassis, while the 128MB cache helps sustain sequential transfers for media libraries and backups.

Questions about this item

Does my laptop need a 2.5-inch 7mm SATA drive bay for this ST1000LM035?

Yes, the drive uses a standard 2.5-inch form factor with a 7mm height and a SATA 6.0Gb/s interface, so the laptop must provide a matching drive bay and SATA connector.

Will this 5400 RPM drive work alongside an older SATA 3.0Gb/s controller in my laptop?

The SATA 6.0Gb/s interface is backward compatible with SATA 3.0Gb/s controllers, so the drive will function at the controller's maximum speed.

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

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