Product identity

This is a 2.5-inch Seagate BarraCuda laptop hard drive with 1TB capacity, 5400 RPM spindle speed and 128MB cache. It connects through a SATA 6.0Gb/s interface and fits the 7mm z-height used by thin-and-light notebooks. The drive is supplied new in bare-drive packaging for system builders and upgrade installers.

Upgrade context

It replaces an older 2.5-inch SATA hard drive of lower capacity or smaller cache, and the jump is worthwhile when a notebook or compact desktop needs more storage without moving to a thicker 15mm bay. The 140MB/s peak data rate improves file-transfer responsiveness over slower legacy drives. Buyers who want solid-state speed or capacities above 2TB should look elsewhere.

Compatibility check

Verify the host system accepts a 2.5-inch SATA drive with a 7mm profile and that a SATA data plus power connector is available. Confirm the BIOS or UEFI recognises 1TB volumes and that no hardware RAID controller imposes a lower capacity limit. The drive is not formatted, partitioned or allocated, so the operating system must initialise it on first boot.

Perguntas sobre este artigo

Will the 7mm 2.5" form factor fit my laptop's drive bay?

The drive measures 7mm high, 69.85mm wide and 100.35mm long, matching the standard 2.5-inch 7mm bay used in most thin-and-light laptops.

What is the correct way to connect the SATA 6.0Gb/s interface during installation?

Align the L-shaped SATA data and power connectors, press firmly until they click, then secure the drive with the laptop's mounting screws or caddy; forgetting to latch the cables is the common mistake.

How often should I check the 128MB cache and 5400 RPM mechanism for long-term health?

Run the manufacturer's diagnostic tool every few months to scan for bad sectors — up to 25 may appear over time — and replace the drive if reallocated sector counts rise.
