I've been running without a swap drive for a long time now, after I noticed I was no longer using any (maybe because I upgraded to 16GB RAM) so I no longer use a swap drive at all for any of my installs of Linux.
if you ever find you need some swap space then you can just create it on the fly. it is called a swap file.
man 1 fallocate
sudo fallocate -l 512M /swapfile
sudo fallocate -l 1024M /swapfile1
sudo mkswap /swapfile
sudo mkswap /swapfile1
sudo swapon /swapfile
you can change the size of the file to whatever you want / need as well as the file name and put it anywhere on your system to use. then swap off, or reboot to turn it off, and you can delete it and make another one later on if you need to.
or keep it then slap it into fstab as a mount to swap?
