Basic disk vs Dynamic Disk


Basic disk & Dynamic Disk

Basic Disk type :

Basic Disk
  • It uses traditional partition tables (MBR or GPT).
  • Supports up to four primary partitions, or three primary partitions plus one extended partition that can contain multiple logical drives.
  • Once partitions are created, their size or structure cannot be changed without deleting or reformatting them.
  • Compatible with all Windows versions and supports multi-boot configurations.
  • Simpler to use and manage, making it suitable for standard desktop or single-OS use.

Dynamic Disk type :

Dynamic Disk
  • Introduced from Windows 2000 onwards, supports more advanced features.
  • Uses Logical Disk Manager (LDM) and can create volumes that span multiple disks (spanned, striped, mirrored, RAID-5).
  • Volumes can be resized, extended, or combined on the fly, even without rebooting in many cases.
  • More complex and flexible, supports advanced storage setups (e.g., software RAID, redundancy).
  • Not suitable for multi-boot with non-Windows systems and less compatible with older Windows versions.
  • Conversion from basic to dynamic disk can be done without data loss, but reverting from dynamic to basic generally requires deleting all volumes on the disk.
