Which data storage class is most suitable for data that must be accessed less than once a year?

The most suitable data storage class for information that needs to be accessed less than once a year is Archive Storage. This storage class is specifically designed for data that is infrequently accessed and has a long retention period. It provides a cost-effective solution for storing such data, as it offers lower storage costs compared to the other options. Archive Storage is optimal for scenarios where retrieval time is not critical, making it ideal for archival purposes, backups, or compliance data that must be preserved for extended periods but is rarely needed.

Other storage classes like Nearline Storage and Coldline Storage are still intended for infrequent access but are designed for slightly different use cases. Nearline is for data that is accessed less than once a month, while Coldline is suitable for data that may need to be accessed less frequently. However, neither of these options meets the criteria of less than once a year as specifically as Archive Storage does. Standard Storage, on the other hand, is intended for frequently accessed data, making it unsuitable for infrequent access requirements. Thus, Archive Storage is the correct choice for data that has such rare access needs.
