For simple storage that does not require configuration, yes.
As all confiuration is normally lost when unplugging and
replugging, KVMs typically simulate KBD/mouse for each
attached computer. This can lead to rather wired compatibility
issues.

Simulate? It doesn't simulate anything, a KVM simply plugs/unplugs
keyboard/mouse between the two PC's just like one of those USB
switches do.

It cannot as USB mice and keyboards have state, and that
state is typically different for the connected computers.

That utterly mangles the story. They dont have state in the sense that there is any
problem with unplugging a replugging the keyboard and mouse with the PC booted up.

In addition, unplugging may cause problems.

Wrong with USB keyboards and mice.

The real reason that the better KVMs simulate the keyboard and mouse
for the PCs those arent currently switched to is so you can boot those
other PCs without them whining about no mouse or keyboard being present.
