HGST Travelstar Z5K500 320GB 7mm drive
The HGST Travelstar Z5K500 is a 2.5 inch internal hard drive with 320GB capacity and a 7mm low profile. It suits users replacing a failed drive in a slim laptop or adding affordable bulk storage to an older portable system. The SATA 3.0Gb/s interface connects directly to standard notebook drive bays without adapters.
SATA 3.0Gb/s interface practical limits
The SATA 3.0Gb/s link caps sequential throughput below the speed of modern solid-state drives. Mechanical latency averages 5.5ms at 5400 RPM, so random access remains slower than flash-based alternatives. The 8MB cache helps smooth small bursts but cannot overcome the physical rotation limit for sustained workloads.
Upgrading from smaller or thicker laptop drives
This drive replaces 2.5 inch drives thicker than 7mm or those with less than 320GB capacity in compatible bays. The jump is worth it when a thinner profile is required for ultraportable chassis or when the extra capacity extends usable space without moving to solid-state pricing.

Questions about this item
Is the 320GB capacity the only option in this Travelstar Z5K500 series?
This listing covers the HTS545032A7E380 model at 320GB; other Z5K500 capacities exist under different model numbers but are not part of this product.
What does the 5400 RPM spindle speed mean for everyday laptop use?
The 5400 RPM rotation gives typical access times around 5.5ms latency, suited to general storage and quiet operation in slim 7mm bays.
How does the SATA 3.0Gb/s interface affect real-world throughput?
The 3.0Gb/s link sets the bus ceiling; actual read and write speeds will stay within that limit and are further shaped by the 8MB cache and 5400 RPM mechanics.
