Dynamic Disk

What Does Dynamic Disk Mean?

Dynamic disks are logical disks that have the ability to utilize multiple hard disks in the computer to provide disk redundancy and mirroring as well as an increase in performance and reliability.


Dynamic disks are native to Windows operating systems and are available in Windows Vista, Server 2008 and later OS versions.

Techopedia Explains Dynamic Disk

Dynamic disks can be integrated with each other, split data over multiple disks and duplicate data. They can contain up to 2000 volumes, where each volume serves as a separate drive or partition. These volumes can be created using MBR- or GPT-based partitioning methods. They utilize a database to manage volumes created on one or more disks.

A computer can create only one dynamic disk group at a time. Dynamic disks are created and managed using Logical Disk Manager (LDM) and Virtual Disk Service (VDS).
