Ideal for laptop storage upgrades

The HGST TravelStar Z5K500 is a 2.5-inch internal hard drive offering 500GB of capacity. It spins at 5400 RPM with an 8MB cache and connects via a SATA 3.0Gb/s interface. This unit is sold new after being erased to DoD 5220.22 M standards and tested for reliable operation.

Limited by SATA 3.0Gb/s throughput

The drive uses the SATA 3.0Gb/s interface, which caps maximum theoretical transfer rates at 3.0 Gb/s. Real-world sustained speeds will be lower and are further constrained by the 5400 RPM rotational speed. This makes the drive suitable for general storage but not for high-performance primary system volumes.

Verify 2.5-inch bay and SATA support

Before ordering, confirm your laptop or enclosure accepts a standard 2.5-inch SATA drive. Ensure the system BIOS or controller recognises drives of this capacity. Note that the drive ships unformatted and unpartitioned, so the operating system must initialise it. Some units may contain up to 25 bad sectors.

商品問答

Which version of the HGST TravelStar Z5K500 should I choose?

The model HTS545050A7E362 is the single 500GB 5400 RPM variant with 8MB cache and a SATA 3.0Gb/s interface.

What does the 5400 RPM rating mean once the drive is installed?

It sets the spindle speed, which influences access latency and sustained throughput for typical laptop workloads.

How does the SATA 3.0Gb/s interface limit real-world performance?

The 3.0Gb/s link defines the maximum bus bandwidth available to the drive, capping peak transfer rates at the SATA II level.
