Microsoft Storage Reserved Capacity Archive 100 TB GRS

Control retention costs without giving up durability. This Microsoft Storage Reserved Capacity commitment reserves 100 TB of Archive storage in US West Central for 1 year, with GRS replication for geographic protection. It is designed for data that must stay retained, recoverable, and cost-efficient over long periods, including compliance archives, backup copies, and historical datasets. Archive tier storage is built for infrequent access, where the economics matter more than retrieval speed. By reserving capacity up front, you gain predictable billing for a defined footprint instead of absorbing variable pay-as-you-go rates. GRS adds another layer of resilience by maintaining replicated copies in a paired region, helping protect against regional disruption. For infrastructure and procurement teams, the value is straightforward: lower unit cost, clearer budget planning, and a storage posture aligned to long-term retention requirements. This is the kind of commitment that makes sense when data volume is known and access patterns are stable. It is not for active workloads; it is for the data you must keep, but rarely touch.
