    Good? Bad? I've read a few results on google and here on MacRumors, but all of them are old and point to systems running about 1GB or 2GB. I have 4GB, I have disabled Paging in Vista and it runs fine, plus it saves my SSD from killing itself.

    hhmm i wonder how much of an impact paging would actually have on the SSD, minimal i would say.... maybe it would let you go past the 5 year mark?

    Enough people use Bootcamp that it's not completely irrelevant. Plus the OP themselves said they use Vista. (FWIW a similar recommendation is made to use "noatime" in Linux, although I'm assuming that's even less likely).

    My thoughts would be these:

    1) There really is no good data to support the rapid SSD failure theory. I don't have VM on my SSD netbook, and it's pretty common practice still to disable that and atime, but other than that, most of us just stopped worrying about it.

    2) Look at your pageouts. If nothing is being paged out to the swap, then what difference does it make? Having a swap file to which nothing is written will certainly not hasten the death of your SSD. On the other hand, it would give you a little more usable space, perhaps. Also, I dunno, is there a way to disable the swap without losing the ability to use SafeSleep? I would think SafeSleep would be worth keeping it there.

    So how does one disable paging on Mac OS X?
    Even on a non-SSD system, it may still come in handy when juice is running out.

    You don't.

    Believe me, you really don't want to do that. OS X expects to be able to swap stuff out, and it doesn't like it when it can't.
