Microsoft Storage Reserved Capacity Cool 1 PB GRS US West Central

Reduce the cost of storing infrequently accessed data without giving up resilience. Microsoft Storage Reserved Capacity for cool data lets you commit to 1 PB in US West Central for 1 year, aligning storage economics with long-retention workloads, backup repositories, and compliance archives. This reservation is designed for teams that know their storage footprint and want to convert variable monthly consumption into a more predictable commitment. With GRS, your data is replicated across paired regions to support durability expectations for business-critical archives and recovery datasets. That makes this option a strong fit when the data is not hot, but it still matters. For procurement and platform teams, the value is straightforward: reserve at scale, reduce exposure to on-demand pricing, and keep capacity planning cleaner over the term. Compared with smaller reservations, the 1 PB commitment is built for environments with sustained, high-volume cool storage demand where pricing stability matters as much as availability.
