Highlights of Dynamic Disk

u Create a large volume that occupies several disks.

u Add fault-tolerance to your system and data, by mirroring a volume—such as the one with

the operating system—to another disk. If a disk with one of these mirrors fails, no data will

be lost on such volume.

u You could create simple volume, spanned volume, striped volume, mirrored volume and

RAID5 volume.

u Simple volume and spanned volume can be expanded to increase their capacity by Windows

built-in Disk Manager.

About Dynamic Volume

Simple volume

u A simple volume consists of disk space from a single dynamic disk.

u Extend a simple volume to another disk and it becomes a spanned volume.

u Add a mirror to a simple volume and it becomes a mirrored volume.

u Simple volumes are not fault-tolerant.

u Simple volumes do not provide improved disk I/O performance.

Spanned volume

u A spanned volume consists of disk space from two or more dynamic disks and all volume

slices do not need to be equally-sized.

u A spanned volume can be extended as long as unallocated space exists in dynamic disks.

u Striped volumes usually provide the ability to access data faster than other types of dynamic

volumes.

u Striped volumes cannot be mirrored or extended and are not fault-tolerant.

u Mirrored volumes cannot be extended and do not provide improved disk I/O performance.

u A mirrored volume is also known as RAID 1 volume.

Raid-5 Volume

u A RAID-5 volume is a fault-tolerant volume. Its data and parity are striped across an array of

three or more dynamic disks.

u Parity is a calculated value that can be used to reconstruct data after a failure.

u When a dynamic disk fails, the portion of the RAID-5 volume that was on that failed disk can

be re-created from the remaining data and the parity.

u RAID-5 volumes cannot be mirrored or extended but provide improved disk I/O performance

Concept of Dynamic Disk

Dynamic Disk: Every physical or virtual disk could be converted to dynamic disk from basic disk

under the Windows built-in Disk Management, and dynamic disk records the data information by

using LDM data pool. As same as basic disk, dynamic disk also support GPT and MBR two types

of partition style too. Dynamic Disk Manager could also support both partition styles.

Dynamic Disk Group: Dynamic disk group is built up with every dynamic disk, and one

Windows OS could only support one dynamic disk group. If one dynamic disk doesn’t belong to

the recognizable disk group, it would be showen as foreign disk and could not be operated. In

File System: It is a method of storing and organizing arbitrary collections of data. A file system

tracks free and occupied space, supports folders and files names, and stores the physical positions

of files on a disk. Examples of file systems that are supported in Windows are FAT16 (also known

could support the maximum 18 EB hard disk and each hard disk could contain at most 128

partitions in Windows OS.

Aomei DDM

Aomei Dynamic Disk Manager (DDM) is an easy-to-use and multifunction dynamic disk and

volume management software, with user friendly operations to assist you to manage the volumes

and dynamic disk. With the help of DDM, you can easily & fast create/delete the volume and the

most advantage is that it can resize/move your volume to readjust the volume on the basis that it

ensures the security of your valuable data. You could also convert your disk from dynamic to basic

or GPT to MBR without deleting any volumes.
