Overview of dynamic disk volumes
On Windows, a disk can use either the basic disk type or the dynamic disk type. A basic disk is the standard choice for most users and works well for common partitions. A dynamic disk supports advanced volume types such as simple, spanned, striped, mirrored, and RAID-5 volumes, making it useful for flexible storage and fault tolerance.

Dynamic disks allow you to span volumes across multiple disks, which is useful when a data volume is running low on space. You can also create a striped volume to distribute data across several hard drives and improve I/O performance. For example, a striped volume made of four disks can read data from all disks at the same time, which may greatly improve performance for demanding tasks.
Dynamic disks can also provide fault tolerance for data protection. Mirroring writes the same data to two disks so the volume can continue working if one disk fails. RAID-5 requires at least three disks and combines striping with parity to balance usable capacity, performance, and fault tolerance.
When do you need to resize a dynamic disk?
Similar to a basic disk, it's sometimes necessary to resize a dynamic disk volume, such as when adding more free space to a volume, especially a system partition, to address low disk space issues. To make efficient use of disk space, users may also need to reduce large or unused volumes to free up unallocated space for smaller partitions. In either case, understanding how to resize a dynamic disk volume is crucial.
Windows native Disk Management: resize dynamic disk free (limited)
To shrink or extend a dynamic disk volume for free in Windows, use the Disk Management Console, which can be launched by pressing WIN + R and entering "diskmgmt.msc". This console allows you to view and configure both basic and dynamic disks.
To resize a dynamic disk volume, right-click the volume and select "Extend Volume" or "Shrink Volume". These options are mainly available for simple and spanned volumes. For striped, mirrored, and RAID-5 volumes, Windows Disk Management offers limited options and may require deleting or recreating volumes. Next, the process of extending a simple dynamic volume is demonstrated step by step.
Step 1. Right-click the dynamic simple volume and select "Extend Volume".
Step 2. Click "Next" in the Wizard window.
Step 3. Select the disk which contains the free space you want to add into the simple volume and click "Next".
Step 4. Click "Finish" to extend the dynamic disk volume. Then you will see the simple volume has been extended.
To shrink a dynamic disk volume, select the target volume, click "Shrink Volume", enter the amount of space to shrink, and follow the wizard to complete the process.
Qiling Disk Master Server: resize dynamic disk volume flexibly
With the Disk Management tool, you can resize dynamic disks in Windows 10, 8, 7, and Windows Server 2003, 2008, 2012, 2016, and 2019, but only for simple and spanned volumes. A more powerful dynamic disk manager, Qiling Disk Master Server, offers additional capabilities.
- Extend and shrink striped volume, mirrored volume, and RAID-5.
