Basic disks are the commonly used storage media with Windows.
They contain partitions like Primary partitions and Logical drives which are typically formatted with a file system.
Dynamic disks offer the ability to create fault-tolerant volumes that may even span multiple disks – which Basic disks cannot.
What happens when you convert to dynamic disk?
The reason for this is simple. A dynamic disk can span multiple drives. If a volume spanned a removable disk and the disk was removed from the system, then the volume would be broken. Another situation in which a basic disk can’t be converted into a dynamic disk is if the basic disk exists on a laptop computer.
What is a dynamic disk?
A disk that has been initialized for dynamic storage is called a dynamic disk. A dynamic disk contains dynamic volumes, such as simple volumes, spanned volumes, striped volumes, mirrored volumes, and RAID-5 volumes. With dynamic storage, you can perform disk and volume management without restarting the Windows.
