Both of them would take the same time as all they do is initiate Async Server-Side Blob Copy. They just tell the service to start copying blob from source to destination. The actual copy operation is performed by Azure Blob Storage Service. The time it would take to copy the blob would depend on a number of factors including but not limited to:

  • Source & destination location.
  • Size of the source blob.
  • Load on storage service.
