Stripped & spanned Volume ??

A spanned volume is made up of 2 or more volumes(up to 32) which can be on multiple disks. The data is written sequentially and so fills up one disk and then goes onto the next.
A stripped volume again consists of multiple volumes but the data is written in stripes across all the volumes. A stripe set must be on at least 2 physical disks. This should give faster access speeds as the system can make use of multiple I/O operations.
In both cases if one disk is lost then all the data on the volume is gone!

Hi,

Both striped disks and spanned volumes are made up of multiple disks.

Example for two disks :

A striped disk's data is evenly distributed across the two disks. When a file is written to the "disk", half is written to one disk and half is written to the other.

Creating a spanned volume on the other hand is like making your disk bigger. You're using a second disk to tack on extra storage onto the first.

When you write to a spanned volume, you write to one disk but when it fillsup, the data spills over to the next disk.

Hope that helps,
Cheers,
Tim.
