Dynamic disk review

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. For many reasons, you need to clone the dynamic disk. Such as the following situations:

1. If you find your computer runs slower and slower, you need to consider whether it is your dynamic running 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, clone dynamic 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, copy 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 data loss, you can find the data on the cloned disk, which would minimize the damage of data loss.


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

Step 3. Next, choose the dynamic disk to convert to basic disk, and click "Next".

Select Dynamic Disk 14gb

Step 4. Finally, click Commit ->Proceed to execute the operation.

Proceed 14gb

* After converting, it will pop-up a window to remind you that to take effect, you must restart your computer.

Select Destination Disk

* If your target hard drive is an SSD, you can check the option of “Optimize the performance of SSD”, which will improve the SSD’s performance.

Step 6. Finally, click Apply ->Proceed.


As so far, you have already cloned your dynamic disk to another disk. If you still need a dynamic disk, you can convert the basic disk to dynamic disk with the Dynamic Disk Manager.

Convert basic disk to dynamic disk

Then enter Disk Management to convert basic disk to dynamic disk.

Dynamic disk is much harder to manage than basic disk. But you can use the AOMEI Dynamic Disk Manager snapped in AOMEI Partition Assistant Professional. It allows you to manage your dynamic disk easily such as resize/move volume, shrink volume, delete/format volume, change label, change letter, add drive to RAID and so on.
