When I fetch VM sizes through the API I get same size for OS-disk for all types of VMs and it's 1TB in size. The allocated storage space seems to be 30GB for example one VM that's using Standard_A1. Is the 1TB max storage that can be allocated per disk? Is there a limit on the blob-storage?

 "/subscriptions/prov_subscr_id/providers/Microsoft.Compute/locations/local/vmSizes?api-version=2016-03-30"

{
                    "name" => "Basic_A0",
           "numberOfCores" => 1,
          "osDiskSizeInMB" => 1047552,
    "resourceDiskSizeInMB" => 20480,
              "memoryInMB" => 768,
        "maxDataDiskCount" => 1
}
{
                    "name" => "Standard_A1",
           "numberOfCores" => 1,
          "osDiskSizeInMB" => 1047552,
    "resourceDiskSizeInMB" => 71680,
              "memoryInMB" => 1792,
        "maxDataDiskCount" => 2
}
{
                    "name" => "Standard_A2",
           "numberOfCores" => 2,
          "osDiskSizeInMB" => 1047552,
    "resourceDiskSizeInMB" => 138240,
              "memoryInMB" => 3584,
        "maxDataDiskCount" => 4
}

The [osDiskSizeInMB] is the OS disk size, in MB, allowed by the virtual machine size.

meaning that if you create a VM with custom script or using ASR the maximum value for OS disk is 1TB. 

the MAX data (resource) disk size currently is 4TB
