Unlike a concatenated device, the slices are addressed in an interleaved manner. That is, as space is needed, it is allocated as a block from the first slice, and then a block from the second slice, and so on.

The main advantage of a striped device is that when the slices are on several physical disks, it provides an increase in performance because it allows multiple simultaneous reads and writes. This is because each physical disk in the striped virtual device can be accessed at the same time. In addition, like ...
