Compact 7 mm laptop hard drive

The HGST Travelstar Z7K320 is a 2.5-inch SATA 3.0Gb/s drive with 250GB capacity, 7200 RPM spindle speed and 16MB cache. It measures 7 mm in height, matching the Z-height used in thin notebooks and external enclosures. The bare-drive package suits system integrators and upgrade installers. Average seek time is 13ms and average latency is 4.2ms.

Suits thin notebook and external builds

Buyers upgrading a slim laptop or a compact external case where a 7 mm SATA drive fits will benefit from the 7200 RPM speed and low 1.8W read/write power. Systems that only accept 9.5 mm drives cannot use this model. Users needing more than 250GB of storage should look at larger capacities.

7 mm Z-height decides fit

The single specification that determines compatibility is the 7 mm physical height. Verify that the target notebook or enclosure explicitly supports 7 mm SATA 2.5-inch drives before purchase.

أسئلة حول هذا المنتج

How can I confirm the drive is running at 7200 RPM after installation?

Listen for the characteristic 7200 RPM spin-up sound and verify the model HTS723225A7A364 appears in your BIOS or disk utility with the correct 250GB capacity.

The listing says "Bare Drive" — does it include mounting screws or a SATA cable, or must I buy them separately?

Bare Drive means only the 2.5-inch mechanism is supplied; you will need to provide any 2.5-inch mounting screws, brackets or SATA data and power cables required by your notebook or enclosure.

I see the Z7K320 series ranges from 160GB to 320GB — why choose this 250GB model over the 320GB version?

The 250GB model uses the same 7200 RPM, 16MB cache and SATA 3.0Gb/s specification as the 320GB drive; select it when 250GB meets your storage need and you prefer the lower cost per drive.
