320 GB 2.5" SATA notebook drive
This HGST Travelstar 5K320 is a 320 GB 2.5 inch internal hard drive built for laptop upgrades and replacements. It connects through a SATA 3.0Gb/s interface and spins at 5400 RPM with an 8 MB cache. The bare-drive packaging suits system builders and DIY installers.
Halogen-free design with standard SATA connectors
The drive uses a halogen-free construction that meets eco-friendly design goals. Its standard SATA data and power connectors fit any 2.5 inch drive bay or caddy without adapters. Low power consumption helps extend battery life in portable systems.
5400 RPM operation keeps heat and noise low
At 5400 RPM the drive runs cooler and quieter than faster spindle speeds, making it suitable for thin-and-light notebooks. Average seek time is 12 ms and average latency is 5.5 ms for typical office and media workloads. Power draw stays modest during normal read and write activity.

Questions about this item
What does the SATA 3.0Gb/s interface cap the transfer speed at in practice?
The SATA 3.0Gb/s link limits maximum throughput to about 300 MB/s, though the 5400 RPM mechanism will typically deliver less.
What physical dimensions and mounting does the 2.5" form factor need?
The drive uses the standard 2.5 inch width and the usual four bottom mounting holes for laptop bays or caddies.
How is this bare drive installed, and what step is often missed?
Connect the SATA data and power cables, secure the drive with screws, then initialise and format the 320GB volume in the OS before use.
