What is dynamic disk Windows?
Dynamic disk and basic disk are two disk types. Both of them support MBR and GPT partition styles. But they are different. Dynamic disk is a physical disk initialized for dynamic storage. It contains simple volumes, spanned volumes, striped volumes (RAID-0), mirrored volumes (RAID-1), and RAID-5 volumes. Because of these different volumes, it provides the features that basic disks do not, like the ability to improve data's efficiency of read-write speed, to create new volumes which span multiple disks, to create fault-tolerant volumes and so on.
Why you need to clone dynamic disk?
If you are using dynamic disk, there must be a large amount of data stored on it. And you might need to clone the dynamic disk for many reasons, including:
1. If you find your computer runs slower and slower, you need to consider whether it is your dynamic runs out of space. Thus, you may need to replace the dynamic disk with a larger one. But you want to keep the old data on the new large disk. Thus, copying the dynamic disk should be the best way to change hard drive without losing data.
2. If your dynamic disk is too old to perform well, you may consider to change it with a brand-new disk. Thus, cloning the dynamic disk should be the best way for keeping old data on the hard drive.
3. You can also clone dynamic disk to another disk simply for backing up. Once the dynamic disk broken or other unexpected things lead to data loss, you can get back the data on the cloned disk, which would minimize the damage of data loss.

In a word, cloning dynamic disk to another hard disk has many advantages. And you need to consider to make a copy file of your dynamic disk.
