Disk space refers to the amount of storage available for your website files, databases, emails, and other data. Choosing the right amount of disk space depends on the size of your website, the number of media files (images, videos, etc.), and how much content you plan to add over time.
Ensure you select a hosting plan with enough disk space to avoid running out of storage, which could slow down your website or cause issues with uploading new content. You can upgrade your hosting plan later if needed.
