What is the difference between Dynamic disk and Basic disk

Before partitioning a drive or getting information about the partition layout of a drive, you must first understand the features and limitations of basic and dynamic disk storage types.

There are two types of disks when referring to storage types in this context: basic disks and dynamic disks. Note that the storage types discussed here are not the same as physical disks or partition styles.

Basic Disks:

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.

Can i add more space to an existing partition in basic disk?

You can add more space to existing primary partitions and logical drives by extending them into adjacent, contiguous unallocated space on the same disk. To extend a basic volume, it must be formatted with the NTFS file system.

The following operations can be performed only on basic 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.

Dynamic Disks:

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).

Dynamic disks offer greater flexibility for volume management because they use a database to track information about dynamic volumes on the disk and about other dynamic disks in the computer.

Note: Don’t covert a disk to dynamic if it contains an OS as dynamic disk will not be able to boot an OS.

The following operations can be performed only on dynamic disks:

  • Create and delete simple, spanned, striped, mirrored, and RAID-5 volumes.
  • Extend a simple or spanned volume.
  • Remove a mirror from a mirrored volume or break the mirrored volume into two volumes.
  • Repair mirrored or RAID-5 volumes.
  • Reactivate a missing or offline disk.

Another difference between basic and dynamic disks is that dynamic disk volumes can be composed of a set of non-contiguous extents on one or multiple physical disks. By contrast, a volume on a basic disk consists of one set of contiguous extents on a single disk.

Common operations to basic and dynamic disks:

  • Support both MBR and GPT partition styles.
  • Check disk properties, such as capacity, available free space, and current status.
  • View partition properties, such as offset, length, type, and if the partition can be used as the system volume at boot.
  • View volume properties, such as size, drive-letter assignment, label, type, Win32 path name, partition type, and file system.
  • Establish drive-letter assignments for disk volumes or partitions, and for CD-ROM devices.
  • Convert a basic disk to a dynamic disk, or a dynamic disk to a basic disk.
