HGST Deskstar 7K160 160GB 3.5" drive

The HGST Deskstar 7K160 is a 3.5-inch internal hard drive with 160GB capacity, 7200 RPM spindle speed and an 8MB cache. It connects through a SATA 3.0Gb/s interface and is supplied as a bare drive in new condition.

Ideal for legacy desktop upgrades and basic storage

This drive suits owners of older desktops that need a direct SATA replacement for a failed or undersized mechanical disk. It is not for builders who want more storage capacity, faster sequential throughput or solid-state responsiveness.

SATA 3.0Gb/s interface decides host compatibility

The drive communicates over a 3.0Gb/s SATA link, so the host controller must support that standard for full rated performance. Average seek time is 8.5ms and features include Native Command Queuing, Thermal Monitoring and Fly Height Control.

Questions about this item

What size drive bay and interface connector does the 3.5" SATA 3.0Gb/s drive require?

The drive fits a standard 3.5" internal bay and connects via a SATA 3.0Gb/s data cable plus a SATA power connector from the PSU.

Which jumper or BIOS setting is often missed when installing this Deskstar 7K160 as a secondary drive?

No jumpers are needed for SATA; the common oversight is forgetting to enable the SATA port in BIOS or initialising the disk in Disk Management before use.

How can I monitor the long-term health of the HDS721616PLA380 and when should I plan replacement?

Use SMART Command Transport data via tools like CrystalDiskInfo; watch for rising reallocated-sector counts or seek-time increases beyond the 8.5ms spec as replacement indicators.
