All of your Azure Storage data objects, such as blobs, file shares, queues, tables, and discs, are stored in an Azure storage account. Your Azure Storage data is accessible from anywhere in the world over HTTP or HTTPS thanks to the storage account’s distinctive namespace, which it offers. Your storage account’s data is enduring and highly available, safe, and incredibly scalable.
Type of Storage Account:
General purpose V2:
The newest type of storage account is called StorageV2, and it combines V1 storage with Blob storage. It provides all the most recent features at a lower price, including access tiers for Blob storage. This account type is preferred by Microsoft over the V1 and Blob storage account types.
You can upgrade a general-purpose v1 storage account or a Blob Storage account to a general-purpose v2 account. Note that this action can’t be undone.

Blob Storage Account
Blob storage is designed to hold large amounts of unstructured data. Unstructured data is information that does not conform to a specific data model or definition, such as text or binary data.
You can upgrade a general-purpose v1 storage account or a Blob Storage account to a general-purpose v2 account. Note that this action can’t be undone.
