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
