Why to convert basic disks to dynamic disks?

Windows 2000 introduces the concept of dynamic disks. It allows you to use basic disks to convert to dynamic disk to take advantage of additional features. When you first install Windows 2000/XP Professional, Vista, Windows 7, Windows 8 and Windows Server 2000/2003/2008, all disks are initialized as basic. You can easily convert basic disk to dynamic disk using 'Convert to Dynamic Disk' option with Windows built-in partition manager without losing any data and get additional features as follows:

  • Disk and volume management tasks are performed without having to restart the computer afterwards.
  • Create volumes that span multiple disks.
  • Extend a simple or spanned volume.
  • Dynamic disks support an unlimited number (up to 2000) of volumes.
  • Dynamic disks do not use a Master Boot Record (MBR). Disk layout information is stored on the last 1 MB of the disk.
  • A dynamic disk can contain simple volumes, spanned volumes, striped volumes, mirrored volumes, and RAID-5 volumes.
