@HemantSudehely-0557 Firstly, apologies for the delay in responding here and any inconvenience this issue may have caused.
I would recommend to use the Azure Blob Storage in this scenario. If you need to mount a drive than you can go for Azure files using SMB protocol.
This article will explain How to upload blobs to container using .Net(v12SDK): https://learn.microsoft.com/en-us/azure/storage/blobs/storage-quickstart-blobs-dotnet#upload-blobs-to-a-container
Additional information: How to connect an app to Azure Storage
Storage considerations for Azure Functions
Hope this helps!
Kindly let us know if the above helps or you need further assistance on this issue.
