HGST Travelstar Z7K500 HTS725025A7E630 250 GB 2.5" laptop hard drive 7200 rpm 32 MB cache

Product identity

The HGST Travelstar Z7K500 is a 250 GB 2.5-inch internal hard drive built for laptops and other slim devices. It spins at 7200 rpm with a 32 MB cache and connects through a SATA 6.0Gb/s interface. The 7 mm height fits thin chassis designs that cannot accept standard 9.5 mm drives.

Who it suits and who it does not

This drive suits builders upgrading a notebook, external enclosure or console that accepts a 7 mm SATA drive and wants mechanical speed at 250 GB capacity. Buyers who need more storage than 250 GB should look at larger capacities in the same series. Users whose systems require a 9.5 mm drive height or a non-SATA interface cannot use this model.

Deciding specification

The 7 mm z-height is the single specification that decides fitment. If the target bay only accepts 9.5 mm drives, this unit will not install. When the bay accepts 7 mm drives, the SATA 6.0Gb/s interface and 7200 rpm spindle deliver the highest mechanical performance available in this form factor.
