Both shared Ultra Disks and shared Premium SSD v2 managed disks are priced based on provisioned capacity, total provisioned IOPS (diskIOPSReadWrite + diskIOPSReadOnly) and total provisioned Throughput MB/s (diskMB/sReadWrite + diskMB/sReadOnly). There's no extra charge for each additional VM mount. For example, a shared Ultra Disk with the following configuration (diskSizeGB: 1024, DiskIOPSReadWrite: 10000, DiskMB/sReadWrite: 600, DiskIOPSReadOnly: 100, DiskMB/sReadOnly: 1) is charged with 1024 GiB, 10100 IOPS, and 601 MB/s regardless of whether it's mounted to two VMs or five VMs.

>[!CAUTION]
>Avoid setting the diskIOPSReadOnly value below 100. Lower values may reduce costs but can negatively impact the startup performance of VMs attached to the disk.
