Debatable; there are several thing to consider:

It may survive, but in systems with a lot of RAM, where swapping is rare
(like my new one with 256GB RAM) you may want to use the SSD space for
things that need to be faster.  On the system I'm describing some daemons
get swapped out because they're never active, but I keep a small swap space
so the kernel can do that.  No need for them to be on SSD.

want to think of how long it would take to fsck my 11-TB RAID without
journaling.
