Microsoft Storage Reserved Capacity Archive 1 PB GRS

Control archive storage costs with a 1 PB reserved capacity commitment for Azure in US West Central. Built for data that must remain available for compliance, legal hold, or operational retention, this reservation pairs archive-tier economics with GRS replication for added resilience across regions. A fixed 1-year term gives finance and infrastructure teams a clearer cost baseline than pay-as-you-go archive consumption, especially when retention volumes are known in advance. It is a practical fit for organizations that want to reduce exposure to fluctuating storage rates while keeping cold data in a durable, low-access tier. Because this is reserved capacity rather than a software feature set, the value is in predictable planning: commit to the capacity you already expect to keep, then align storage governance, retention policy, and budget ownership around a defined term. For teams managing regulated records or large historical datasets, that predictability matters as much as the storage tier itself.
