A 320GB desktop HDD is a hard disk drive with a storage capacity of 320 gigabytes, designed for use in desktop computers. It’s suitable for light to moderate storage needs, such as storing documents, photos, and smaller applications. While it offers decent space for basic usage, it’s relatively small by modern standards, especially for gaming, video editing, or large data storage. It typically operates at 7200 RPM, providing a balance of performance and reliability for everyday tasks. However, for larger storage needs, users often upgrade to higher-capacity drives.
