  • Question

  • Hi everybody,

       Is there any difference between dynamic disk and basic disk in performance?

    thanks

  • Hi,


    A basic disk uses primary partitions, extended partitions, and logical drives to organize data. A formatted partition is also called a volume (the terms volume and partition are often used interchangeably). In this version of Windows, basic disks can have either four primary partitions or three primary and one extended partition. The extended partition can contain multiple logical drives (up to 128 logical drives are supported). The partitions on a basic disk cannot share or split data with other partitions. Each partition on a basic disk is a separate entity on the disk.

    Dynamic disks can contain a large number of dynamic volumes (approximately 2000) that function like the primary partitions used on basic disks. In some versions of Windows, you can combine separate dynamic hard disks into a single dynamic volume (called spanning), split data among several hard disks (called striping) for increased performance, or duplicate data among several hard disks (called mirroring) for increased reliability.

    With basic disks, you can do the following:

    Format partitions and mark them as active
    Create and delete primary and extended partitions
    Create and delete logical drives within extended partitions
    Convert from a basic disk to a dynamic disk

    With dynamic disks, you can do the following:

    Create and delete simple, striped, spanned, mirrored, and RAID-5 volumes
    Remove a mirror from a mirrored volume
    Extend simple or spanned volumes
    Split a volume into two volumes
    Repair mirrored or RAID-5 volumes
    Reactivate a missing or offline disk
    Revert to a basic disk from a dynamic disk (requires deleting volumes and reloading)

    Hope these could be helpful.

  • hello,

    There's no difference in perfomance.

    The difference is how the disk is used, either as partition or volume.

    The basic disk contains primary/secondary partitions, logical drivers.

    Using dynamic disk you have possibility to:

    " 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

  • of course, if you convert your disks to dynamic and create a RAID volume (like 0, 1 or 5) you can improve the performance of the system and also the reliability (RAID 1 or 5).

    But the simple action of only converting to dynamic disk doesn't provide better performance.
