The new disks provide up to 4TB of disk space. These new sizes allow you to perform up to 250 MBps of storage throughput and 7,500 IOPS.
Two new disk sizes were introduced,
- P40 (2TB) and P50 (4TB) for Managed/unmanaged Premium Disks;
- S40 (2TB) and S50 (4TB) for Standard Managed Disks.
For Standard unmanaged disks, you can create disks with maximum size of 4095 GB.
These new sizes are currently only available to use now in the West US Central Region using Azure PowerShell and CLIs through ARM.
Availability is being expanded and rolled out in the Azure Portal support around the world in more regions in the next month or so.
New versions of the Azure tools will be created to support upload of VHDs more than 1TB.
