Azure difference between General-purpose v2 storage accounts and BlockBlobStorage accounts explained?

Question

I want to create some new storage accounts in Azure. Naturally, I want to know which are best suited and cheapest for different cases. As far as I can tell the only relevant accounts for me are "General-purpose v2 accounts" and "BlockBlobStorage accounts", but I have a bit of a problem understanding the exact difference in performance and costs. Could anyone elaborate?

Regarding costs of the accounts, I found some information here for V2 and BlockBlobs pricing, but I am not really sure if they really represent the storage classes from Azure (as the naming is a bit of).

Answer 1

For performance, BlockBlobStorage accounts provide low, consistent latency and higher transaction rates. So it has good performance.

For cost(here is the link to pricing page), since BlockBlobStorage accounts does not support tiering to hot, cool, or archive access tiers, it will cost more than General-purpose v2 accounts. General-purpose v2 accounts support tiering like hot / cool / archive, which costs little, please refer to the screenshot as below:

And the link for V2 pricing in your question is incorrect, it's for azure data lake storage v2 which is different than General-purpose v2 accounts.
