In the past, it was quite quiet about new features and announcements in the Azure IaaS space. Yes, sometimes there were new VM sizes with more cores or more RAM, but in general there were no surprising announcements last year. From my point of view, this has changed with MS Inspire, which is currently underway.
Microsoft announced, surprising from my point of view, a new Disk SKU for Azure VMs called Premium SSD v2 Disk. The last announcement in this area was 2019 with the introduction of Ultra Disks.
Premium SSD v1 vs v2
Premium Disk v2 have a maximum limit of 64 TB capacity and delivers 80,000IOPS on a troughput of 1,200MB. The really interesting thing is the baseline performance about 3,000IOPS with a throughput of 125MB. In the v1 variant the IOPS performance depends on the selected disk size, in comparison v2 gives 3000IOPS baseline performance regardless of the size.
Azure VMs that support v2
All Azure VMs that supports Premium Disks supports also the new V2 variant.
Pricing is a bit confusing due to the increased flexibility. Premium SSD v2 are priced hourly based on reserved size, power and throughput. This means you pay a fixed price for baseline performance of 125 MB throughput and 3000 IOPS and additional performance is charged accordingly.
The V1 variant can be used as OS and data disk, the V2 option is currently only possible as data disk.
The Preview is actual only available by request and only in the both regions East US and West Europe and actual not be used for production workloads.
