HGST Travelstar Z5K320 160GB 5400 RPM Laptop Drive
The HGST Travelstar Z5K320 is a 2.5-inch internal hard drive with 160GB capacity and a 5400 RPM spindle speed. It uses a SATA 3.0Gb/s interface and includes 8MB of cache. The 7mm z-height design allows it to fit thinner notebook chassis as well as standard 9.5mm bays.
Sustained Operation at 5400 RPM with Low Power Draw
Under continuous workloads the drive maintains its 5400 RPM speed while consuming 1.6W during read and write activity. Idle power drops to 0.55W, helping extend battery life in portable systems. Average seek time is 13ms with 5.5ms average latency. The 400G operating shock rating protects data during movement.
Straightforward 2.5-Inch SATA Installation
Installation follows the standard 2.5-inch SATA procedure: connect the data and power cables, then secure the drive in the bay. The bare-drive packaging means no mounting screws or adapter brackets are included. The 7mm height fits most modern ultrabooks, but some older laptops require a 9.5mm spacer that is not supplied.

Questions about this item
How much power does the HGST Travelstar Z5K320 draw during continuous read/write use?
The drive consumes 1.6W during read/write operations and drops to 0.55W at idle, helping extend battery life in notebooks.
Does the 7mm height of this 2.5" SATA drive require a spacer or adapter for my laptop bay?
At 7mm z-height it fits modern slim bays directly; a 9.5mm bay will need a 2.5mm spacer which is not included with the bare drive.
Will the SATA 3.0Gb/s interface work reliably with an older SATA 1.5Gb/s controller in my legacy notebook?
Yes, the SATA 3.0Gb/s interface is backward compatible with 1.5Gb/s hosts and will operate at the lower speed without configuration.
