Travelstar 7K100 60GB laptop drive

The HGST Travelstar 7K100 HTS721060G9SA00 is a 2.5-inch internal hard drive built for notebooks. It spins at 7200 RPM with an 8MB cache to deliver desktop-like responsiveness in a mobile form factor. The 60GB capacity suits operating-system installs or modest data storage in older machines. Buyers who need more storage will find the capacity limiting.

SATA 1.5Gb/s interface limits

The drive connects through a SATA 1.5Gb/s interface, capping theoretical throughput at 1.5 gigabits per second. Average seek time is 10ms, average write time is 11ms and average latency is 4.2ms. These figures reflect the mechanical and bus constraints of the platform. Systems requiring faster sequential or random access will not reach higher speeds with this interface.

Bare drive installation notes

The unit ships as a bare drive without mounting brackets, cables or screws. Installation follows standard 2.5-inch SATA procedure: secure the drive in the bay, attach the data and power connectors, and initialise the volume in the operating system. Compatibility issues usually arise when a notebook BIOS does not recognise the drive geometry or when the SATA controller lacks legacy 1.5Gb/s support.

The 7200 RPM spindle delivers desktop-like performance with a 10 ms average seek time and 4.2 ms latency.

How does the SATA 1.5 Gb/s interface limit real-world transfer rates?

The SATA 1.5 Gb/s link caps the maximum interface throughput to 1.5 Gb/s, below the drive's own cache speed.
