Dell 320 GB 5400 RPM SATA HDD

This 2.5 inch internal hard drive provides 320 GB of storage for desktop PCs and compatible laptops. It suits users who need basic capacity for documents, backups or a secondary data volume. The drive is supplied in new condition.

5400 RPM rotational speed

The platters spin at 5400 RPM, which determines the sustained transfer rate and access latency. Buyers who require faster random performance for operating-system drives or heavy workloads should consider a solid-state alternative.

Low power draw and quiet operation

A 5400 RPM mechanism typically draws modest power and generates minimal acoustic noise during normal desktop use. The 8 MB cache helps smooth small read and write bursts without increasing thermal output.

  • 320 GB capacity stores large media libraries
  • 5400 RPM spindle speed delivers steady throughput
  • 8 MB cache buffers frequent read requests

Questions about this item

What real-world speed should I expect from the 5400 RPM platters inside a laptop or desktop?

The 5400 RPM rotation and 8 MB cache deliver typical mechanical hard-drive throughput; the SATA 3 Gb/s interface sets the bus ceiling.

Does the SATA 3 Gb/s interface limit how fast this drive can read or write?

Yes, the SATA 3 Gb/s link is the maximum bus speed for this model; actual rates depend on the 5400 RPM mechanism and 8 MB buffer.

Will the 2.5 inch form factor fit my standard drive bay or caddy?

The drive uses a 2.5 inch SATA form factor, so it fits any 2.5 inch bay or adapter designed for that size.
