Windows 7 Disk Management Spanned Volume vs Striped Volume

hard drive

Im looking for a reason why a person would use a Spanned volume rather than a Striped volume?

If my understanding is correct

Striped:  Faster read/write speed than spanned, but I "assume" more wear+tear
Spanned:  No speed benefit like striped, but data is written sequentially and 
          fills up Drive1 before filling up Drive2, so it saves on wear+tear

Beyond that Im not sure if there is any other deciding factor on which to use.

Definition found below:

A striped volume uses the free space on more than one physical hard
disk to create a bigger volume. Unlike a spanned volume, a striped
volume writes across all volumes in the stripe in small blocks,
distributing the load across the disks in the volume. The portions of
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.

Best Answer

A spanned volume can be extended, but not a stripped.

A failure of eiher drive in a stripped volume will result in a total loss. You may be able get some data back from a spanned volume if the file is completly on one disk.

If you do not have a good backup system, then I suggest you don't use either option.
