Currently, Premium SSD v2 disks can't be attached to VMs with encryption at host enabled. Currently, taking snapshots isn’t supported, and you can't create a Premium SSD v2 from the snapshot of another disk type. Currently, Premium SSD v2 disks can't be attached to VMs in virtual machine scale sets. Currently, Premium SSD v2 disks can only be attached to zonal VMs. Premium SSD v2 disks can't be used as an OS disk. However, a respondent outworlder on a Hacker News thread stated there are quite some limitations: You can dynamically scale up or scale down the IOPS and throughput as needed without downtime, allowing you to manage disk performance cost-effectively while avoiding the maintenance overhead of striping multiple disks to achieve more performance. In addition, Aung Oo, General Manager, Azure Storage, explained in an Azure blog post the key benefit of Azure Premium SSD v2 Disk Storage: The Premium SSD v2 is well-suited to a broad range of production workloads such as – SQL Server, Oracle, MariaDB, SAP, Cassandra, Mongo DB, big data/analytics, gaming, on virtual machines or stateful containers. Furthermore, Premium SSD V2 has five types of persistent disks. With Premium SSD v2, customers can now provision up to 64TiBs of storage capacity, 80,000 IOPS, and 1,200 MBPS throughput on a single disk.Ĭompared to Premium SSD (first version), the IOPS performance depends on the selected disk size, yet v2 provides a 3000 IOPS baseline performance regardless of the size. This managed disk offering provides customers with high throughput and high input/output (IO) for Azure virtual machines (VMs). 
The last update around Azure Disk Storage was in 2019 with the introduction of Ultra Disks. This new disk offering provides, according to the company, the most advanced block storage solution designed for a broad range of input/output (IO)-intensive enterprise production workloads that require sub-millisecond disk latencies as well as high input/output operations per second (IOPS) and throughput-at a low cost. Recently Microsoft announced the preview of Premium SSD v2, the next generation of Microsoft Azure Premium SSD Disk Storage.
