  • Total capacity320 GB
  • Interface typeSATA 1.5Gb/s
  • Form factor2.5 in (6.35 cm)
  • Packaging typeBare Drive
  • Cache memory8 MB
  • Average seek time12 ms

  • 5400 RPM spindle speed balances performance and quiet operation
  • 8 MB cache improves data access responsiveness
  • SATA 1.5 Gb/s interface ensures broad laptop compatibility

Suitable for older SATA laptops

This 320GB drive fits 2.5-inch bays using the SATA 1.5Gb/s interface. It spins at 5400 RPM with an 8MB cache and a 12ms average seek time. The bare-drive packaging suits repair technicians and integrators. Rated for 300000 MTTF hours, it is sold in new condition.

Not for speed-critical or high-capacity needs

The 5400 RPM spindle and SATA 1.5Gb/s link limit throughput compared with faster drives. Users who need quicker boot times or sustained transfers should consider a solid-state alternative. The 320GB capacity may also be tight for modern operating systems and large media libraries. Builders requiring a 6Gb/s interface or larger cache must look elsewhere.

Interface is SATA 1.5Gb/s

This specification determines whether the drive will operate at its rated speed in a given notebook. Older chipsets that support only the 1.5Gb/s generation will work natively. Newer controllers are backward compatible but will not increase the drive's native transfer ceiling. Verify the laptop's SATA generation before purchase.

Questions about this item

Will the SATA 1.5Gb/s interface work with my older laptop that only supports SATA 1.5Gb/s?

Yes, the drive uses a SATA 1.5Gb/s interface which matches your laptop's SATA 1.5Gb/s capability. The 2.5" form factor fits standard laptop bays.

How can I confirm the 5400 RPM drive is performing correctly after installation?

Listen for normal mechanical operation and verify the drive appears in BIOS with the correct 320GB capacity. Run a diagnostic tool to check the 12ms average seek time and SMART data for errors.

Does the bare drive include mounting screws or a SATA cable, or must I buy them separately?

The bare drive includes only the hard drive unit. Mounting screws and SATA cables are not included and must be purchased separately if your laptop does not already have them.
