The paging/swapping device is logically an extension of main memory: why not just buy some more main memory? Simpler, less i/o traffic and system overhead, and probably cheaper (more vendors). Such devices are TOO GOOD for backing store; they are much better used for root or /tmp, which are NOT logically just extensions of memory.
