Suits older notebook repairs only

Technicians restoring vintage laptops that require a native IDE connection will find the correct interface and physical size here. The 4200 RPM speed and 12ms seek time match period specifications. Buyers needing higher throughput or larger capacities should consider other options.

IDE Ultra ATA100 interface decides fit

The drive connects exclusively through the legacy parallel IDE bus labelled Ultra ATA100 or ATA-6. Systems lacking this specific connector cannot use the device. Verify the host interface before purchase.

Questions about this item

Is the 80GB capacity the only option for the Travelstar 80GN series?

The Travelstar 80GN series is defined by its 80GB capacity, so this model represents the single capacity point for that specific series.

What does the 4200 RPM speed mean for everyday laptop use?

The 4200 RPM spindle speed prioritises lower power draw and quieter operation over peak transfer rates, suiting basic office tasks and older system upgrades.

What does the IDE Ultra ATA100 interface limit in practice?

The IDE Ultra ATA100 interface caps the maximum burst transfer rate at 100 MB/s, which is the ceiling for data moving between the drive cache and the host controller.
