HGST Deskstar 7K160 80 GB SATA drive
The HGST Deskstar 7K160 is a 3.5-inch desktop internal hard drive with 80 GB capacity. It spins at 7200 RPM and provides an 8 MB cache on a SATA 3.0 Gb/s interface. The bare drive uses Native Command Queuing for data throughput.
Suits legacy desktop repair and low-capacity storage
This drive fits older desktop systems that require a SATA 3.0 Gb/s mechanical drive for boot or secondary storage. It is not for buyers who need more capacity than 80 GB, nor for builds that demand solid-state speeds or modern high-density platters.
SATA 3.0 Gb/s interface decides compatibility
The single specification that decides fit is the SATA 3.0 Gb/s interface. Your motherboard or controller must provide a matching SATA port; systems that only support newer or different interfaces cannot use this drive.

Questions about this item
How does the 7200 RPM spindle speed affect everyday use?
The 7200 RPM rotation keeps data moving quickly, so operating system boots and application launches feel responsive on a desktop system.
What does the SATA 3.0Gb/s interface limit in practice?
The SATA 3.0Gb/s link caps maximum throughput at roughly 300 MB/s, so sustained reads and writes will not exceed that ceiling.
Will this 3.5 inch drive fit a standard desktop bay?
Yes, the 3.5 inch form factor matches the regular desktop drive bay and uses standard SATA power and data connectors.
