There are many differences between basic and dynamic disks. A basic disk denotes a disk that includes partitions (logical drives, primary partitions) and is usually formatted via a file system to be file storage. This type of disk storage is simple and adapts to many storage situations; they also support clustered disks and USB drives. By using basic disks, one can create and remove primary/extended partitions, format partitions/make active, and create and remove logical drives.
Dynamic disks, on the other hand, can create volumes on multiple disks (striped/spanned volumes) and create fault-tolerant volumes, such as using a Redundant Array of Independent Disks (RAID). Dynamic disks offer higher flexibility for volume control and increased fault-tolerance. By using dynamic disks, one can create and remove spanned, striped, simple, mirrored, and RAID volumes as well as extend spanned or simple volumes. They also allow the reactivation of missing or offline disks.
Although any size business can benefit from the increased fault tolerance in dynamic disks, the larger the company, the more advanced the system would need to be. In a small business, merely using dynamic disks would be a cost-effective way of protecting its data. In a larger company, a combination of local and array-based RAID would be ideal. If a company wanted to convert from one style of disk storage to another, switching from basic to dynamic can be done without problems, however, switching from dynamic to basic can be problematic. Although, software is available that can make these transitions easier.
