General Availability of Premium Azure File Shares

Ronald Mariah · June 28, 2019

Azure now supports hosting File Shares on Premium backed storage media (SSDs) and are useful for IO-intensive workloads, hosting databases and high-performance computing (HPC).

The easiest way to create a Premium File Share is using the Azure CLI

az group create --name myresourcegroup --location westeurope

az storage account create `
    --name mypremiumfileshare `
    --resource-group myresourcegroup ` 
    --location westeurope `
    --sku Premium_LRS `
    --kind FileStorage

Some limitiations on Premium File Shares:

  • Only supports LRS (Locally redundant storage)
  • There is no automatic way to convert a File Share on Standard storage to Premium.

There are alternate ways to get the content stored in Standard storage to Premium

  • Azure Import/Export
  • Azure File Sync
  • AzCopy
  • Robocopy
