title: Azure Key vault vs Storage encryption
body: <p>I have premium storage account for which I enabled Encryption just after creating this and I found this link  <a href="https://docs.microsoft.com/en-us/azure/storage/storage-service-encryption" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/azure/storage/storage-service-encryption</a> to check whether blob are encrypted or not.</p>
  
  <p>Now if I encrypt OS disk and data disk using Azure key vault which is also used to protect data at rest but encrypted storage account also does same thing. Could any one explain what difference among these two. I know about keys, secrets etc. so I don't want this diff.</p>
