Capacity and interface

The HGST Travelstar 5K100 is a 100GB 2.5-inch laptop hard drive with a SATA 1.5Gb/s interface. It spins at 5400 RPM and includes an 8MB cache. The bare drive is supplied new and is intended as a direct replacement for compatible notebooks.

Who this suits and who should look elsewhere

This drive fits older laptops that require a SATA 1.5Gb/s mechanical drive with a 2.5-inch form factor. Its low power consumption and 600,000 load/unload cycles support mobile use. Buyers who want more storage capacity, a faster spindle speed or a modern SATA revision should look elsewhere.

Deciding specification

The SATA 1.5Gb/s interface is the specification that determines whether this drive will work in a given system. Compatibility depends on the notebook accepting a 1.5Gb/s SATA connection and a 2.5-inch drive bay.

Questions about this item

Is the 100GB capacity the only option in the Travelstar 5K100 series?

The HTS541010G9SA00 model is the 100GB version of the Travelstar 5K100 series. Other capacities exist in the same series but are sold under different model numbers.

What does the 5400 RPM speed mean for everyday laptop use?

The 5400 RPM spindle speed combined with 12ms average seek time and 5.5ms latency delivers quiet, low-power operation suited to general office tasks and media playback.

Will the SATA 1.5Gb/s interface limit performance in a modern laptop?

The drive uses the first-generation SATA 1.5Gb/s interface, which caps the maximum burst transfer rate at 1.5Gb/s regardless of the host controller version.
