What is a dynamic disk (Windows 7)?

Dynamic disk and basic disk are two types of disk. By comparison, the dynamic disk is more flexible than a basic disk because it uses a hidden logical disk manager or virtual disk service to keep track of all dynamic volumes on the disk. On a basic disk, you can create primary drive, extended drive, and logical drives. On a dynamic disk, with special information tracking method, you are allowed to create volumes that span across many disks such as the spanned or striped volumes, and fault-tolerant volumes like RAID-5 or mirrored volumes.

However, in Windows 7, the dynamic disk does not support RAID-5 volume. The RAID 0 and RAID 1 are supported. The RAID 0 always refers to striped volume can improve disk I/O performance but cannot offer fault tolerance. The RAID 1 means the mirrored volume, which is a fault-tolerant volume and provides data redundancy by duplicating the information contained on the volume. If one of the disks fails, the data can still be accessed from the remaining disk.

Can Windows 7 install on dynamic disk?

From above, we know dynamic disk has 5 different volumes and allows you to do much more than a basic disk. So, do you want to install Windows 7 on the dynamic disk? Do you know what versions of Windows 7 support dynamic disk?
In general, Windows 7 (or Windows 8) supports two disk storage types: basic and dynamic. But not all Windows 7 editions realize dynamic disk configuration. Dynamic disks are only supported for Windows 7 Professional, Enterprise and Ultimate Editions. You can not convert basic disk to dynamic in Windows 7 Starter, Home Basic and Premium Editions. So only Windows 7 Professional, Enterprise and Ultimate Editions can install on dynamic disk.
