To support user profile containers with SMB multichannel and low-latency SSDs while minimizing costs, which type of storage account is recommended?

The recommended storage account for supporting user profile containers with SMB multichannel and low-latency SSDs, while also minimizing costs, is Premium file shares. Premium file shares are specifically designed for scenarios that require high performance and low latency, making them suitable for applications that benefit from the SMB protocol, such as Azure Virtual Desktop environments.

Using SMB multichannel allows users to take advantage of multiple network connections to increase throughput and redundancy. Additionally, Premium file shares utilize SSD storage, which provides the fast read and write speeds necessary for applications that require quick access to user profiles, enhancing the overall user experience.

In contrast, while premium block blobs and premium page blobs provide high-performance storage capabilities, they are not optimized for SMB access, which is crucial for user profile containers in the context of Azure Virtual Desktop. Standard general-purpose v2 storage accounts, on the other hand, offer lower performance levels and higher latency compared to premium options, making them less ideal for scenarios where speed and responsiveness are paramount.
