Locally Redundant Storage (LRS) - Replicates your data three times within a single data center in the primary region, offering protection against hardware failures but not against data center or regional outages.

Zone-Redundant Storage (ZRS) - Replicates your data synchronously across three Azure availability zones in the primary region, providing protection against data center failures but not regional outages.

Geo-Redundant Storage (GRS) - Replicates your data to a secondary region that is hundreds of miles away from the primary region, providing protection against regional outages but does not allow read access to the secondary region unless there is a failover.

Read-Access Geo-Zone-Redundant Storage (RA-GZRS) - Combines the benefits of ZRS in the primary region with geo-replication to a secondary region, and allows read access to the data in the secondary region without requiring a failover, ensuring high availability and durability.

Geo-Zone-Redundant Storage (GZRS) - Similar to RA-GZRS but does not provide read access to the secondary region without a failover, offering a balance between cost and redundancy.
