HGST Deskstar 80 GB SATA drive

The HGST Deskstar HDS721680PLA380 is an 80 GB 3.5-inch internal hard drive that spins at 7200 RPM and connects through a SATA 3 Gb/s interface. It carries an 8 MB buffer and is supplied in new condition for desktop storage upgrades or legacy system repairs.

Sustained workload behaviour

During continuous read or write sequences the 7200 RPM spindle keeps data flowing at the SATA 3 Gb/s link rate without the pauses seen on slower drives. The 8 MB cache absorbs short bursts so that extended transfers stay smooth across the full capacity.

Thermals noise and power

Typical desktop operation keeps the drive within normal temperature limits for a 3.5-inch mechanical unit and acoustic output remains at the low hum expected from a 7200 RPM mechanism. Power draw follows standard SATA 3.5-inch specifications so no special cooling or supply considerations are required.

Questions about this item

How much heat and noise does the 7200RPM Deskstar produce during all-day operation?

The 7200RPM spindle and 3.5" form factor generate typical desktop drive heat and audible seek noise; ensure your case has adequate airflow over the drive bay.

What host connection does the HDS721680PLA380 require to work?

It needs a motherboard or controller with a standard SATA 3Gb/s port and a matching SATA data cable plus a SATA power connector from the PSU.

Will this 80GB SATA drive work alongside my older PATA drives on the same system?

Yes, SATA and PATA operate on separate controllers; the drive appears as a standard SATA device without interfering with legacy IDE channels.
