How to create an Azure premium file share

Premium file shares are offered on solid-state disk (SSD) storage media and are useful for IO-intensive workloads, including hosting databases and high-performance computing (HPC). Premium file shares are hosted in a special purpose storage account kind, called a FileStorage account. Premium file shares are designed for high performance and enterprise scale applications, providing consistent low latency, high IOPS, and high throughput shares.

This article shows you how to create this new account type using the Azure portal, Azure PowerShell module, and the Azure CLI.

Prerequisites

Create a FileStorage storage account

Every storage account must belong to an Azure resource group. A resource group is a logical container for grouping your Azure services. When you create a storage account, you have the option to either create a new resource group, or use an existing resource group. Premium file shares require a FileStorage account.
