What is the benefit of volume encryption compared to full disk encryption?

Volume encryption offers the distinct advantage of being able to apply encryption selectively to specific volumes or partitions, rather than encrypting the entire disk. This flexibility means that users can choose which data to encrypt based on sensitivity or regulatory requirements, allowing for targeted security measures. As a result, organizations can balance performance and security by encrypting only the volumes that contain sensitive or critical data while leaving less sensitive information unencrypted to enable faster access or optimized storage management.

While full disk encryption provides comprehensive security by protecting all data on a disk, it may not be necessary or efficient for all situations. Volume encryption allows for more nuanced security strategies, accommodating various operational needs without sacrificing security where it's not essential.
