Yes, consider the purpose of why a disk cache is better than RAM cache:
objects are not erased when Squid or the system restarts.

==> tmpfs data is erased when Squid or the system restarts. So why bother?

All you gain from tmpfs is a drop in speed accessing the data, from RAM
speeds down to the Disk speeds. Whether it is SSD or HDD that is slower
than RAM.
