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.
