Microsoft Azure Blob Storage Plans Pricing
Azure Blob Storage is priced per access tier (Hot, Cool, Cold, Archive), with separate charges for capacity (per GB-month), transactions (per 10,000 ops), retrieval (per GB), and egress. Premium block blob accounts use SSD-backed pricing at higher rates. Reservation discounts available via 1- or 3-year capacity reservations.
