Disadvantages of dynamic disks


On a fresh installation of Windows 8 ( 4 primary partitions ) I've mistakenly converted the disk to dynamic, from Disk Management.

What are the disadvantages of a dynamic disk?

Unable to install other OS on other partition?

Any other problems?

Thank you!

Hi Sorin,

Thank you for posting your query on Microsoft Community.

Dynamic disks provide features that basic disks do not, such as the ability to create volumes that span multiple disks (spanned and striped volumes) and the ability to create fault-tolerant volumes (mirrored and RAID-5 volumes). Like basic disks, dynamic disks can use the MBR or GPT partition styles on systems that support both. All volumes on dynamic disks are known as dynamic volumes.

Basic disks are the storage types most often used with Windows. The term basic disk refers to a disk that contains partitions, such as primary partitions and logical drives, and these in turn are usually formatted with a file system to become a volume for file storage. Basic disks provide a simple storage solution that can accommodate a useful array of changing storage requirement scenarios. Basic disks also support clustered disks, Institute of Electrical and Electronics Engineers (IEEE) 1394 disks, and universal serial bus (USB) removable drives.

The following operations can be performed only on basic disks but not on Dynamic disks.

  • Create and delete primary and extended partitions.
  • Create and delete logical drives within an extended partition.
  • Format a partition and mark it as active.

Some more differences between Basic and Dynamic discs.

  • Basic Disks use a Partition Table to manage all partitions on the basic disk. Dynamic Disks use a hidden LDM database to manage all volumes on the dynamic disk.
  • Basic Disks once create a partition, you can not change its capacity, unless use third-party tools. Dynamic Disks without restarting system expand the capacity of volumes, and don’t loss of data.
  • Basic Disks, the maximum capacity of a partition (volume) can be limited to 2TB. Dynamic Disks can well handle the large partition of more than 2TB.
  • Basic Disks only can create any primary or logical partition. Dynamic Disks can create simple volume, spanned volume, striped volume, mirrored volume and RAID-5 volume.
