These are faster and less prone to damage from power outages, but they can hog space on your real disks. A VHD file can be of fixed size, or it can start small and expand as necessary dynamically expanding. A fixed size is slightly faster and slightly more robust in power-off situations.

The dynamically expanding option can be better if you need to save space. Because storage space for backups fills rapidly, I generally choose to use dynamically expanding VHDs. Note that the default size is defined in megabytes.

Next, specify a location to store the file and specify the size in MB or GB. Choose whether the disk type will be fixed size or dynamically expanding. The new disk will need to be initialized.

Right-click on the disk and choose Initialize Disk. Now that the disk is initialized, you need to create the volume. VHD Set files support online resizing of shared virtual disks, support Hyper-V Replica, and can be included in application-consistent checkpoints. VHD Set files store checkpoint information about the group virtual disk used in guest clusters, in the form of metadata.

Hyper-V handles all aspects of managing the checkpoint chains and merging the shared VHD set. Management software can run disk operations like online resizing on VHD Set files in the same way it does for. VHDX files. This means that management software doesn't need to know about the VHD Set file format.
