250 GB SATA notebook drive

The HGST Travelstar 5K500.B is a 2.5 inch hard drive with 250 GB capacity and a SATA 3.0 Gb/s interface. It spins at 5400 RPM and includes 8 MB cache for everyday notebook, external enclosure or console storage upgrades.

Low power consumption and quiet operation

The drive is highlighted for the lowest power consumption in its class and a halogen-free design that reduces heat output. Average seek time is 12 ms and average latency is 5.5 ms, contributing to quiet, cool running in slim chassis.

Bare drive with standard 2.5 inch mounting

Supplied as a bare drive without cables or brackets, it fits any 2.5 inch SATA bay using the industry-standard connector layout. The 3.0 Gb/s link works with older and newer SATA controllers alike for simple drop-in replacement.

Questions about this item

How do I install the 2.5" SATA drive in a notebook, and what step is often missed?

Mount the 2.5" drive in the bay, connect the SATA data and power cables, then initialise and format the 250GB volume in the operating system before use.

What maintenance or replacement will the Travelstar 5K500.B need over time?

No scheduled maintenance is required; replace the drive if SMART attributes report reallocated sectors or if the 5400 RPM mechanism develops excessive noise or read errors.

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

The 5400 RPM platter speed and 8MB cache constrain sustained throughput well below the 3.0Gb/s link ceiling during long sequential workloads.
