Capacity and interface
The HGST HTS541680J9AT00 is an 80GB 2.5-inch laptop internal hard drive with an IDE Ultra ATA100 / ATA-6 interface. It suits owners of legacy notebooks or industrial equipment that require a direct IDE connection. The Travelstar 5K160 series uses perpendicular magnetic recording for data integrity. This bare drive arrives new without mounting hardware or cables.
Sustained workload behaviour
At 5400 RPM with an 8MB cache the drive delivers steady throughput for sequential reads and writes during extended sessions. Average seek time of 11ms and average latency of 5.5ms remain consistent rather than spiking under continuous load. The mechanism is rated for high reliability in mobile environments where vibration is present. Performance scales predictably with the IDE bus limit of 100 MB/s.
Thermals noise and power
The unit is highlighted for best-in-class low-power utilisation, drawing minimal current from the notebook supply during typical operation. Acoustic output stays low enough for quiet office or bedroom use. Heat generation remains modest so standard laptop chassis airflow is sufficient without extra cooling. The 3-year limited manufacturer warranty reflects confidence in thermal endurance.

Questions about this item
How much power does the 5400 RPM Travelstar 5K160 draw during all-day operation?
The drive is highlighted for best-in-class low-power utilisation, making it suitable for extended laptop use without excessive battery drain.
What interface must the laptop provide for this bare 2.5" IDE drive to work?
The notebook needs an IDE Ultra ATA100 / ATA-6 connector; no adapter or caddy is included with the bare drive.
Will the 80GB IDE Ultra ATA100 drive function in a legacy notebook that only supports ATA-5?
The ATA-6 interface is backward compatible with ATA-5 hosts, so the drive will operate at the slower ATA-5 transfer rate.
