250 GB SATA laptop drive
The HGST Travelstar 5K500.B HTS545025B9A300 is a 2.5‑inch internal hard drive with 250 GB capacity, 5400 RPM spindle speed and 8 MB cache. It connects over a SATA 300 interface and is built for notebook PCs, external enclosures, gaming consoles and other mobile applications. The drive uses halogen‑free production and carries an EcoTrac classification for low power consumption.
Suits storage‑focused upgrades.
This drive fits users who need affordable bulk storage for documents, media libraries or game installs in a laptop or console. It is not suited for workloads that demand SSD‑level responsiveness or sustained high‑throughput performance. Buyers who require faster random access or lower latency should consider alternative technologies.
SATA 300 interface decides compatibility
The single specification that determines fit is the SATA 300 (3 Gbit/s) interface. Verify that the host system provides a standard 2.5‑inch SATA bay and a matching data connector before purchase. Capacity is fixed at 250 GB and spindle speed at 5400 RPM, so the drive cannot be reconfigured for higher performance tiers.

Questions about this item
How do I install this 2.5 inch SATA drive in a laptop?
Slide the drive into the 2.5 inch bay, connect the SATA data and power cables, then secure it with the caddy screws. The step often missed is tightening the caddy so vibration does not loosen the SATA connector.
Will the 8 MB cache or 5400 RPM spindle need replacement later?
The cache and spindle are sealed inside the drive and are not user-serviceable. If the drive fails, the whole unit is replaced; no separate cache or motor swap is possible.
What limit appears first during sustained writes on this SATA/300 interface?
The 5400 RPM platter speed and 8 MB buffer set the sustained throughput ceiling, so the mechanical write speed is reached before the SATA/300 link saturates.
