# Block Volumes Block volumes function as a storage solution comparable to a portable external drive that you might use with your personal computer. This storage type enables you to maintain and organize data separately from your computing instances. These volumes can be connected to an instance for various purposes such as file storage, database management, or application hosting, and subsequently disconnected and transferred to a different instance when necessary. Block volumes provide adaptability, dependability, and versatility for diverse computing tasks, delivering expandable storage capacity that adjusts to meet your evolving requirements.
