Explanation:
A striped volume is a dynamic volume that stores data in stripes on two or more physical disks. Data in a striped volume is allocated alternately and evenly (in stripes) across the disks. Striped volumes offer the best performance of all the volumes that are available in Windows, but they do not provide fault tolerance. If a disk in a striped volume fails, the data in the entire volume is lost.

You can create striped volumes only on dynamic disks. Striped volumes cannot be extended. You can create a striped volume onto a maximum of 32 dynamic disks.

Backup Operator or Administrator is the minimum membership required to complete the actions below.
