The portions of the disk used to create the volume need to be the same size; the size of the smallest free space included in the striped volume will determine. It can contain disk space from 2 to 32 hard disks, and the data is divided into blocks of 64KB.
How to create a Striped Volume in Windows
The physical disks in a striped volume do not need to be identical, but there must be unused space available on each disk that you want to include in the volume. You cannot increase the size of a striped volume after it is created.
Change the size of Striped Volume in Windows
To change the size of a striped volume, you must first complete the following steps: A striped volume works well in the following situations:
When users need rapid read access to large databases or other data structures.When storing program images, dynamic-link libraries (DLLs), or run-time libraries for rapid loading. Operating systems such as Windows 2000 that use memory-mapped images can benefit from using striped volumes.When collecting data from external sources at very high transfer rates. This is especially useful when the collection is done asynchronously.When multiple independent applications require access to data stored on the striped volume. When the operating system supports asynchronous multi-threading, which helps load balance disk read and write operations.
It is faster to read or write the data from a striped volume than from a spanned volume, but however, striped volumes are not fault-tolerant. It is therefore important to backup striped volumes regularly. Sourced from Technet Magazine & Technet Library.
