Understanding of the Volume in Windows





Simple Volume
           Simple volume is a dynamic volume that encompasses available free space from a single, basic, or dynamic hard-disk drive. It is a portion of a physical disk that functions as though it were a
physically separate unit. A simple volume can consist of a single region on a disk or multiple regions of the same disk that are linked together. Simple volumes have the following characteristics:
• Not fault tolerant. Disk failure leads to volume failure.
• Volume I/O performance is the same as disk I/O performance.

Mirrored Volumes
           Mirrored volume presents two disks to the operating systems as a single logical volume. A
mirrored volume always consists of exactly two disks. Each disk has an identical copy of the data
that is on the logical volume.

Spanned Volumes
           Spanned volume joins areas of unallocated space on at least two, and at most 32 disks, into a
single logical disk. Similar to a spanned volume, a striped volume also requires two or more disks.
However, striped volumes map stripes of data cyclically across the disks.

Striped Volumes
           Striped volume also is known as a RAID-0 volume. A striped volume combines equal-sized areas of unallocated space from multiple disks.
           It also a well suited for isolating the paging file. By creating a volume where Pagefile.sys
is the only file on the entire volume, the paging file is less likely to become fragmented, which helps improve performance. Redundancy is not required for the paging file normally. Striped volumes provide a better solution than RAID-5 for paging file isolation. This is because the paging file activity is writeintensive, and RAID-5 is better suited for read performance than write performance.
