Capacity and interface

This GoHardDrive 120GB 3.5" internal hard drive uses a SATA 3.0Gb/s interface and spins at 7200 RPM. It suits desktop PCs, NAS units, external enclosures and CCTV DVRs that need basic storage for daily computing tasks.

Thermals and power

The 7200 RPM spindle speed produces modest heat and audible seek noise typical of mechanical drives. Power draw stays within normal 3.5" SATA limits during everyday file access and background backup operations.

Sustained load behaviour

Under continuous read or write workloads such as video surveillance recording or large batch transfers the drive maintains its 7200 RPM speed. The 2MB cache buffers small bursts but sustained throughput is limited by the SATA 3.0Gb/s link and platter density.

Questions about this item

How do I install the 3.5" SATA drive and which step is often missed?

Mount the drive in a 3.5" bay, connect the SATA data and power cables, then initialise and format the 120GB volume in Disk Management — the formatting step is the one most people forget.

What maintenance or replacement will the 7200 RPM drive need over time?

Mechanical drives degrade with use; plan to replace the unit once SMART reallocated-sector counts rise or after several years of daily computing workloads.

What limit appears first during sustained transfers on the SATA 3.0Gb/s interface?

The 3.0Gb/s SATA link caps sequential throughput well below the 7200 RPM platters' potential, so the interface bottleneck shows up first during long writes.
