Scenario: A company needs to store large volumes of archival data with infrequent access. Which storage solution, disk or tape libraries, would be more cost-effective and efficient for this scenario?

Tape libraries are more cost-effective and efficient for storing large volumes of archival data with infrequent access. Tape provides higher storage capacity at a lower cost per gigabyte compared to disk. Since the data is accessed infrequently, the slower access times of tape are acceptable, making it an ideal choice for long-term storage needs.
