  2. Hot
  3. Cool

    anonymous user Welcome to Microsoft Q&A, Thank you for posting your query here!

    Go for the Cool trier : If you are not using the data frequently

    • Hot tier - An online tier optimized for storing data that is accessed or modified frequently. The Hot tier has the highest storage costs, but the lowest access costs.
    • Cool tier - An online tier optimized for storing data that is infrequently accessed or modified. Data in the Cool tier should be stored for a minimum of 30 days. The Cool tier has lower storage costs and higher access costs compared to the Hot tier.
    • Archive tier - An offline tier optimized for storing data that is rarely accessed, and that has flexible latency requirements, on the order of hours. Data in the Archive tier should be stored for a minimum of 180 days.

    Pricing and billing: All storage accounts use a pricing model for block blob storage that is based on a blob's tier. Keep in mind the billing considerations described in the following sections.

    For more information about pricing for block blobs, see Block blob pricing.

    Data in the cool access tier can tolerate slightly lower availability, but still requires high durability, retrieval latency, and throughput characteristics similar to hot data. For cool data, a slightly lower availability service-level agreement (SLA) and higher access costs compared to hot data are acceptable trade-offs for lower storage costs.
