Which of the following can be a benefit of Content Addressable Storage?

Virtualizing multiple storage arrays is a feature of storage virtualization, which is a broader concept not specific to Content Addressable Storage.

While CAS data can be accessed, its primary benefit is not superior ease of data sharing compared to other storage types or protocols.

Content Addressable Storage (CAS) systems assign a unique address (a cryptographic hash) to data based on its content. This design inherently allows the system to detect and avoid storing redundant copies of identical content, thus achieving single instance storage and optimizing storage capacity.

CAS systems are generally optimized for data integrity and archival storage, not necessarily for achieving the highest levels of I/O performance.
