About RAID 5 volumes
Dynamic volumes are a new feature of Windows 2000 and can only be created on dynamic disks. With dynamic disks, you are no longer restricted to four volumes per disk. There are five types of dynamic volumes: simple, spanned, mirrored, striped, and RAID-5. You can see details on what is dynamic disk and synamic volume.
A RAID-5 volume is a fault-tolerant volume whose data is striped across three or more disks, and it possesses the ability to offer a greater flexibility for windows server and optimize disk I/O performance. That means when a portion of RAID 5 volumes fails, the data on the other disks will be untouched.
Volumes on dynamic disks will also be running out of space, then how to fix low disk space problem on dynamic disk? Windows built-in disk management can resize dynamic volumes, but it can only work on simple and spanned volumes, not including striped/mirrored/RAID 5 volumes. Don’t worry; this article will introduce two ways to expand RAID 5 volumes.
