I haven't done any measurements but it's likely fairly close
to the same number of disk writes as yum.  I'd guess that the
biggest cost for yum in particular is the RPM metadata - for
Fedora it's huge.  (rpm-ostree with package layering pays this
same cost, but you can avoid it with custom tree composes of course).  

I'd be more concerned about sources of constant writes like having the
systemd journal be persistent.
