250 GB Travelstar 5K320 for laptops

This 2.5 inch SATA hard drive provides 250 GB of storage for notebooks and compact desktops. The 5400 RPM spindle and 8 MB cache suit everyday office work and media libraries. It is a new drive from the HGST Travelstar 5K320 line.

Build and daily fit

The standard 2.5 inch form factor slides into most laptop bays and drive caddies without adapters. A SATA 3Gb/s connector handles both data and power through a single cable. The 1.0 pound weight keeps the system light for mobile use.

SATA 3Gb/s practical limits

The 3Gb/s interface caps sequential throughput below modern 6Gb/s drives. Random access speeds reflect the 5400 RPM rotation rather than solid-state responsiveness. Buyers who need faster boot times or heavier multitasking should consider a solid-state alternative.

Questions about this item

Does the 3 Gb/s SATA interface cap the 250 GB drive's throughput in practice?

The 3 Gb/s SATA link limits the HTS543225L9A300 to about 300 MB/s maximum burst speed, while the 5400 RPM platters and 8 MB cache deliver sustained rates well below that ceiling.

What physical space and connectors does the 2.5-inch SATA drive need to fit?

The drive requires a standard 2.5-inch drive bay or caddy and the usual SATA data and power connectors.

How is the HTS543225L9A300 installed, and what step do people often get wrong?

Mount the drive in the bay, attach the SATA data and power cables, then initialise and format the 250 GB volume in the operating system; skipping the initialisation step leaves the disk invisible.
