Azure Sentinel Azure Blob Long Term Storage & Costs

Hi !

We want to use Azure Blob Storage for long term storage of our Azure Sentinel Instance. There is an logic app available for the automatic export. My questions are now regarding pricing og blob storage.

I think cold storage as storage type is sufficient for our use case. But I have some questions to costs that are additional to data storage prices like operations and data transfer prices in context to azure sentinel like:

Write operations (per 10,000)

What is the number 10000 ? lines ? api calls ?

Will this write also count on initial export or only if I change existing datasets ?

Read operations (per 10,000)

What is the number 10000 ? lines ? api calls ?

Is this the whole daily exportet dataset that will be queried or only the filtered output )

List and Create Container Operations (per 10,000) - is this neccessary for azure sentinel ?

Can anybody help me on this topic ?

Thanks
