160 GB laptop hard drive for notebook upgrades

The HGST Travelstar 5K500.B is a 2.5 inch internal hard drive with 160 GB capacity and a 5400 RPM spindle speed. It uses a SATA 3.0Gb/s interface and includes an 8 MB cache. The drive is designed for notebook PCs, external enclosures, gaming consoles and other mobile applications where low power consumption matters.

Check SATA connectivity and 2.5 inch bay clearance

Verify that the target system has a free SATA 3.0Gb/s port and a standard 2.5 inch drive bay or caddy. The bare drive ships without mounting brackets, cables or adapter hardware. Confirm the operating system can recognise a 160 GB volume and that the BIOS or UEFI supports SATA drives of this capacity.

Halogen-free design with Iterative Detection Read

The drive features a halogen-free construction for an eco-friendly footprint and the lowest power consumption in its class. Its Iterative Detection Read Channel improves signal processing for better reliability. Average seek time is 12 ms and average latency is 5.5 ms. The bare-drive packaging means you must provide your own screws and any required caddy for installation.

Questions about this item

Does the bare drive include a mounting bracket or SATA cable, or must they be purchased separately?

The drive is supplied as a bare 2.5" unit only; any mounting bracket, screws or SATA data/power cables must be sourced separately.

The supplier title lists 0A57911 and 545016 — which part number should I use when ordering?

Both refer to the same model; HTS545016B9A300 is the primary MPN and 0A57911 is the alternate ordering code.

What real-world throughput can I expect from the SATA 3.0Gb/s interface on a laptop?

The 3.0Gb/s link caps at roughly 300MB/s, but the 5400 RPM mechanism with 8MB cache typically delivers well below that in everyday use.
