What is the difference between a fixed size virtual disk and a dynamic virtual disk?

What is fixed VHD?

A fixed-size VHD simply takes up the entire space that is allotted to it during VM creation. The VHD size does not change when data is created or deleted. For example, if you create a 127 GB fixed VHD, then it means 127 GB disk space of the host storage will be dedicated for this VHD alone.

Fixed sized VHD

More robust than dynamic or differencing VHD due to the lack of block allocation tables (i.e. redirection layer). File-based storage container has more management advantages than pass-through disk. Expanding is available to increase the capacity of VHD.

How do I know if my VHD is dynamic or fixed?

You can check your VM discs and then check your actual vhd size, so if your VM report a 200GB disc and your vhd is 65GB, it is a dynamic disc.

When installing a new virtual hard disk Why is it better to use a dynamically expanding virtual hard disk rather than a fixed size virtual hard disk?

When you create a virtual hard disk, it is a good idea to make it a dynamically expanding virtual hard disk. The advantage of a dynamically expanding VHD is that the host PC sees the disk as the size you assign it -- say a 50 GB hard disk -- but the disk actually only uses as much storage space as it needs.

How long should you keep a snapshot?

Do not use a single snapshot for more than 72 hours. The snapshot file continues to grow in size when it is retained for a longer period. This can cause the snapshot storage location to run out of space and impact the system performance.

What type of virtual hard disk is larger in initial stage?

Fixed size Disk

When you create a fixed-size virtual hard disk, space is reserved beforehand. Suppose you created a VHDX of 200 GB, then 200GB space will be reserved for you on the hard disk of the host.

What are the advantages of a dynamically expanding disk when compared to a fixed disk?

Dynamic disks grow as you fill them with data. For example, if you create a fixed disk of 2 TB, the . vhdx file on the host will be 2 TB even if the disk is empty. With a Dynamic disk, it will start out at almost zero, and only grow as you add data to it.
