Deskstar 7K160 160 GB IDE drive

The HGST Deskstar 7K160 is a 3.5-inch desktop hard drive with 160 GB capacity, 7200 RPM spindle speed and an 8 MB cache. It connects through an IDE Ultra ATA133 / ATA-7 interface and is supplied as a bare drive in new condition. Average seek time is 8.5 ms and the unit includes thermal monitoring with fly-height control for reliability.

Suits legacy IDE systems only

This drive fits older desktops or industrial equipment that still use a parallel ATA interface and need a modest 160 GB volume. Builders working with modern motherboards that lack an IDE connector, or anyone requiring higher capacity or faster transfer rates, should consider a different storage solution.

Interface decides compatibility

The sole specification that determines whether this is the correct part is the IDE Ultra ATA133 / ATA-7 interface; the host must provide a matching 40-pin connector and support the ATA-7 command set for the drive to function.

Questions about this item

Will my motherboard need an IDE Ultra ATA133 connector to install this 160GB Deskstar 7K160?

Yes, the drive uses an IDE Ultra ATA133 / ATA-7 interface so the board must provide a matching 40-pin IDE header.

Can I keep an older IDE drive on the same cable while adding this 7200 RPM model?

Both devices will share one IDE channel; set the Deskstar as master and the older drive as slave, or use cable select, and the system will recognise each 160GB and legacy volume.

How do I verify the 8MB cache and 8.5ms seek time are active after fitting the bare drive?

Run the manufacturer’s diagnostic utility or check SMART data — it will report the cache size, rotational speed, and seek performance for the HDS721616PLAT80.
