Desktop internal 320 GB hard drive

The Western Digital Caviar Blue WD3200AAKX is a 3.5 inch SATA hard drive built for everyday desktop workloads. Its 7200 RPM spindle speed and 16 MB cache suit general family and business computing tasks such as operating system boot, document storage and light media playback. Buyers who need more storage capacity or faster random-access speeds for large databases will find this model limited.

Installation basics and common issues

The drive fits a standard 3.5 inch bay and connects through a SATA 6 Gb/s data cable plus a SATA power connector. No special drivers are required on modern operating systems. The most frequent problems are loose data or power cables, incorrect BIOS boot order and forgetting to initialise and format the volume in disk management before use.

Capacity headroom and limits

At 320 GB the drive holds a typical operating system, office applications and a moderate photo or music collection with room to spare. It runs out quickly when storing large video libraries, modern game installations or system images, at which point a higher-capacity drive or a secondary disk becomes necessary.

Questions about this item

How can I verify the WD3200AAKX is running at 7200RPM after installation?

Check the drive's reported rotational speed in your BIOS or use a tool like CrystalDiskInfo; it should show 7200 RPM for this Caviar Blue model.

What comes in the box with the WD3200AAKX and do I need separate SATA cables?

The drive ships as a bare 3.5" SATA unit; you must supply your own SATA data cable and a SATA power connector from your PSU.

Which capacity of the Caviar Blue WD3200AAKX should I choose for a desktop boot drive?

This specific model is the 320GB version; if you need more space, look for a higher-capacity Caviar Blue drive with a different model number.
