Capacity and form factor

The HGST Travelstar 7K750 is a 2.5-inch internal hard drive offering 750GB of storage. It spins at 7200 RPM with a 16MB cache and connects via a SATA 3.0Gb/s interface. The drive measures 9.5mm in height, 70mm wide and 100mm long, and is supplied as a bare drive in new condition.

Who this suits

This drive suits users upgrading a laptop or compact desktop that accepts a 9.5mm 2.5-inch SATA drive and wants 7200 RPM performance. It is not for systems limited to 7mm drive bays, nor for platforms requiring a faster interface than SATA 3.0Gb/s.

Deciding specification

The 9.5mm z-height is the critical measurement; verify your device accepts this thickness before purchase. The SATA 3.0Gb/s interface and 750GB capacity are fixed by the model HTS727575A9E362.

Questions about this item

How do I install this 9.5mm 2.5in SATA drive and what step is often missed?

Mount the drive using the four bottom screw holes, connect the SATA data and power cables, then initialise the 750GB volume in Disk Management — the step most people skip.

What maintenance will this 7200RPM Travelstar 7K750 need later?

No scheduled maintenance is required; keep the 9.5mm enclosure ventilated, run occasional SMART checks and replace the drive if reallocated sectors appear.

What limit appears first during sustained transfers on the SATA 3.0Gb/s link?

The 3.0Gb/s SATA interface caps sustained throughput, so long sequential reads or writes from the 750GB platters will hit that bottleneck before the 16MB cache fills.
