Microsoft Storage Reserved Capacity 10 PB LRS US West Central

Control long-term storage cost without sacrificing regional placement or durability planning. Microsoft Storage Reserved Capacity for cool data reserves 10 PB of locally redundant storage in US West Central for a 1-year term, giving infrastructure teams a cleaner way to forecast spend for retention-heavy workloads. This reservation is built for organizations that keep large datasets online but infrequently accessed: backup repositories, compliance archives, log retention, media libraries, and analytics staging. By committing to reserved capacity, you reduce exposure to variable pay-as-you-go pricing while preserving the flexibility of Azure storage services in the selected region. The LRS model keeps data within a single datacenter cluster for locally redundant protection, making it a practical fit when regional residency and cost efficiency matter more than cross-region replication. For teams managing multi-petabyte footprints, the value is not just lower unit cost — it is budget certainty at scale, with a defined term and a known capacity commitment. Choose this reservation when you need to align storage economics with steady-state demand and avoid paying premium rates for capacity you know will remain in place.
