Using volumes and volume sets
You create volume sets and RAID arrays on dynamic drives. With a volume set, you can create a single volume that spans multiple drives. Users can access this volume as if it were a single drive, regardless of how many drives the volume is spread over. A volume that’s on a single drive is referred to as a simple volume . A volume that spans multiple drives is referred to as a spanned volume .
With a RAID array, you can protect important business data and sometimes improve the performance of drives. RAID can be implemented by using the built-in features of the operating system (a software approach) or by using hardware. Windows Server 2012 R2 supports three levels of software RAID: 0, 1, and 5. RAID arrays are implemented as mirrored, striped, and striped with parity volumes.
You create and manage volumes in much the same way in which you create and manage partitions. A volume is a drive section you can use to store data directly.
NOTE With spanned and striped volumes on basic disks, you can delete a volume but you can’t create or extend volumes. With mirrored volumes on basic disks, you can delete, repair, and resync the mirror. You can also break the mirror. For striped with parity volumes (RAID-5) on basic disks, you can delete or repair the volume, but you can’t create new volumes.
