Zswap always(?) uses a swap file or disk partition. It does a smart job using both compressed memory and disk space as swap

zRam does not use disk. Do not attempt combining zRam with any kind of swap on disk, it's a horrible combination

Oh okay, so zswap actually requires a swap file or device? Or just uses it if available?

[-] Die4Ever@retrolemmy.com 2 points 4 days ago

I think it might require it, but I've never tried it without.
