HP HTS723232A7A364 320GB 7200RPM SATA 2.5in internal hard drive

SKU CH-ZQBA-E49ZV

A 320 GB internal hard drive spinning at 7200 RPM with a 16 MB cache and 2.5 inch SATA 3Gb/s interface

  • 320GB capacity stores large media libraries
  • 7200RPM spin speed accelerates file access
  • 16MB cache buffers frequent read operations
  • SATA 3Gb/s interface connects to most laptops
  • Quiet acoustics and shock protection suit mobile use

Capacity and interface

This HP HTS723232A7A364 is a 320GB 2.5in SATA internal hard drive spinning at 7200RPM with a 16MB cache. It suits laptop owners or small-form-factor desktop builders who need a straightforward mechanical drive for everyday storage.

Thermals noise and power

The drive is described with quiet acoustics and low power consumption, so it runs cooler and draws less current than higher-capacity mechanical disks. A 7200RPM spindle still produces audible seek noise, but the acoustic tuning keeps it suitable for quiet rooms.

Build and mounting

TrueTrack Technology and superior shock protection help the heads stay on track when the chassis moves, a practical benefit for portable use. The standard 2.5in SATA connector and 3Gb/s interface drop into any compatible bay or caddy without adapters.

Questions about this item

How do I install the 2.5in SATA drive in a laptop bay and what step is often missed?

Slide the drive into the 2.5in bay, secure it with the mounting screws or caddy, then attach both the SATA data and power connectors; the step often missed is fastening the drive so it cannot shift under vibration.

What maintenance or replacement will the HTS723232A7A364 need over its life?

No routine maintenance is required; plan to replace the drive if SMART attributes report reallocated sectors or if the 7200RPM mechanism develops audible bearing noise after extended use.

What limit appears first during sustained transfers on the 3Gb/s SATA link?

The 3Gb/s SATA interface caps sustained throughput well below the 7200RPM media speed, so the interface becomes the bottleneck during long sequential reads or writes.
