What good is a dynamic disk?

April 19, 2009



Which of these features are NOT exclusive to dynamic disk storage?

A) Spanning of multiple disks to create a single large volume

B) Splitting of files across multiple physical disks (striping)

C) Duplicating of files across multiple physical disks (mirroring)

D) Creation of both primary and extended partitions


The answer: D) Creation of both primary and extended partitions

The creation of primary and extended partitions can be accomplished on both basic disks and dynamic disks.

The incorrect answers:

A) Spanning of multiple disks to create a single large volume
In basic disk configurations, each separate physical hard drive would be referenced as a separate volume. With dynamic disks, multiple physical disks can be configured to appear as a single large volume.

B) Splitting of files across multiple physical disks (striping)
The only way to enable RAID striping across disks is to configure the disks as dynamic disk storage subsystems.

C) Duplicating of files across multiple physical disks (mirroring)
Another RAID technique is to duplicate data across multiple physical disks for redundancy and fault-tolerance. This type of storage is only available on dynamic disks.

Before you can use a disk in Windows, it must first be partitioned and formatted with an appropriate file system. In this video, you’ll learn how to partition a disk and understand which file systems are available for use in Windows.
