Basic drives and dynamic drives are two types of hard drive
configurations in Windows. Most personal PCs are configured as basic drives, which are
the simplest to manage. Advanced users and IT administrators can make use of dynamic
drives, which use multiple hard drives within a computer to manage data, usually for
increased performance or reliability.
A basic drives use primary
partitions, extended partitions, and logical drives to organize data. A formatted
partition is also called a volume (the terms volume and partition are often used
interchangeably). In this version of Windows, basic drives can have either four
primary partitions or three primary partitions and one extended partition. The
extended partition can contain multiple logical drives (up to 128 logical drives are
supported).
Dynamic drives can contain
a large number of dynamic volumes (approx. 2000) that function like the primary
partitions used on basic drives. In some versions of Windows, you can combine
separate dynamic hard drives to a single dynamic volume (spanned volume), split data
among several hard drives (striped volume) for increased performance, or duplicate
data among several hard drives (mirrored volume) for increased reliability.
