Microsoft Storage Reserved Capacity 10 PB RA-GRS 3 Years

Keep large data estates predictable with reserved cool storage capacity built for long retention windows and controlled access patterns. This Microsoft Azure reservation provides 10 PB of cool storage in US West Central with RA-GRS replication, giving infrastructure teams a clear path to capacity planning without constant exposure to variable consumption pricing. For organizations managing backup repositories, compliance archives, analytics staging, or disaster recovery copies, reserved capacity helps align storage economics with known demand. The cool access tier is designed for data that is not read frequently but must remain immediately available when needed. RA-GRS adds an additional layer of geographic durability by maintaining a read-accessible secondary copy in a paired region. A 3-year commitment is well suited to teams that already understand their retention profile and want to convert recurring storage spend into a more controlled operating model. At this scale, the value is not just lower unit cost — it is budget certainty, capacity assurance, and the confidence to keep critical data online across a defined term.
