Which storage should host FSLogix profile containers on SSDs at lowest cost?

Why the Answer Is Correct

Azure Files Premium exposes file shares backed by solid-state drives, so it satisfies the explicit SSD requirement for FSLogix profile containers. Azure Files is a fully managed PaaS service, meaning no file server clusters, no OS patching, and no storage-account VM maintenance, which directly satisfies "minimize administrative effort." Microsoft's AVD storage guidance lists Azure Files as a supported FSLogix profile store and notes that premium file shares are intended for highly I/O-intensive workloads such as user profile containers. Between the two SSD-capable options in this question, Azure Files Premium is the cheaper and simpler choice, so it also satisfies "minimize cost." The combination of SSD-backed performance, zero infrastructure management, and lower price than Azure NetApp Files makes D the only option that meets all three requirements simultaneously.

Why the Other Options Are Wrong

Azure NetApp Files (A) does deliver SSD-backed, high-performance SMB shares and is a supported FSLogix target, but it requires provisioning NetApp accounts, capacity pools, and volumes, and it carries a materially higher price point, so it fails both the minimize-effort and minimize-cost requirements. Azure Files Standard (B) is the cheapest Azure Files tier, but standard file shares are HDD-backed, which breaks the explicit SSD requirement. Azure Blob Storage Premium (C) is SSD-backed and cheap, but blob storage is not a supported protocol for hosting FSLogix profile containers, which require an SMB share such as Azure Files or Azure NetApp Files. Only Azure Files Premium satisfies the protocol, media type, effort, and cost constraints at once.

Community Comment Notes

As afbnfz noted, the instinctive reaction is "I would've expected this to be Azure NetApp Files but nope, it is actually D," backing it with Microsoft's statement that "Premium file shares enable highly I/O-intensive workloads." pangchn walked the same elimination path, using the Microsoft FSLogix storage article to rule out blob storage and then ruling out Standard because of the SSD rule, leaving Azure Files Premium versus Azure NetApp Files with Premium assumed cheaper. DallasM, Karl_Anthony_Towns, ESAJRR, and Magis all converged on the same letter without dissent, so community consensus is unusually clean here. The remaining nuance worth remembering is that Azure NetApp Files becomes attractive only when scale, latency, or multi-protocol needs outweigh the cost requirement stated in this question.
