Travelstar 7K320 160GB 7200 RPM
The HGST Travelstar 7K320 HTE723216L9A300 is a 160GB 2.5-inch laptop hard drive spinning at 7200 RPM with 16MB cache. It suits owners of older notebooks or legacy systems needing a direct SATA replacement drive.
SATA 3.0Gb/s interface limits
The drive connects through a SATA 3.0Gb/s interface, capping sustained throughput below modern SSD speeds. Average seek time is 12ms and average latency is 4.2ms, so random access remains mechanical.
160GB capacity and mechanical headroom
The 160GB capacity holds a modest operating system, core applications and a small media library. It runs out quickly with large game installs, video projects or multi-boot setups. Buyers who want more storage or silent solid-state speed should consider a different technology.

Questions about this item
Which capacity in the Travelstar 7K320 range suits a typical laptop upgrade?
The 160GB model provides a balance of space and speed for everyday workloads.
What does the 7200 RPM rating mean for daily use?
Faster platter rotation cuts average seek time to 12ms and latency to 4.2ms, so applications and files open more quickly than on slower drives.
How does the SATA 3.0Gb/s interface limit real-world transfer rates?
The link caps at 3.0Gb/s, so sustained reads and writes cannot exceed that bandwidth even though the drive has a 16MB cache.
