Microsoft Storage Reserved Capacity Archive 100 TB RA-GRS

Keep infrequently accessed data protected and budgeted with Microsoft Storage Reserved Capacity for Archive tier storage. This reservation secures 100 TB of capacity in the US West Central region for a 3-year term, helping teams plan retention costs with far greater certainty than pay-as-you-go storage. Archive tier is built for data that must be retained for compliance, legal hold, backup retention, or long-term records management, where access is rare but durability and recoverability still matter. RA-GRS adds geo-redundant resilience with read access to the secondary region, supporting continuity planning for critical archives. For infrastructure and procurement teams, reserved capacity is about more than discounting storage. It is a commitment to stable operating expense, cleaner forecasting, and fewer surprises as retention volumes grow. This makes it a strong fit for organizations with steady archive footprints that can justify a 3-year commitment in exchange for lower effective storage cost. Use this reservation when your archive workload is established, your region is fixed, and your retention policy is measured in years rather than months. It is designed for teams that value predictable economics and resilient storage architecture over short-term flexibility.
