Advantages of dynamic volumes

One of the main advantages of dynamic volumes is that they can span across multiple disks. You can get better use of your available disk space by combining areas of unallocated space in the volumes that go across multiple disks. Multi-disk volumes also improve disk performance by letting more than one disk drive read and write data. Finally, multi-disk volumes let you use RAID technology to make volumes fault tolerant.

When you upgrade a disk so that it can contain dynamic volumes, Storage Foundation writes a small database onto the upgraded disk that contains volume management information about the disk and all other dynamic disks in its disk group. This database gives a dynamic disk additional advantages, which are as follows:
