    Is a swap even necessary with an SSD since they are so fast? I would think overall speed would be to in the following, fastest first:

    SSD Swap + RAM
    No SSD Swap + RAM
    HD Swap + RAM

    You'll usually only get page-outs when your low on main memory (RAM), in those case's you'll be glad you have a fast SSD.

    If you were to run out of memory with paging (what your calling "Swap") disabled, the OS would most likely crash.
