Can you think of a reason why it would be different from any other
electrical device?

What about the energy cost of building a new one when your current one
dies prematurely because you've been turning it on and off too often?
Don't know what the figures would be, but it's not an open and shut
case, that's for sure.

I believe it used to be accepted that running a drive 24/7 would wear
out the bearings faster than turning it on only when it was being used.
But I wonder if the same is true for these liquid bearings? If bearing
wear is not a factor anymore, then running it 24/7 would seem to be a
safer way to go than turning it on and off all the time, because of the
electrical stress that occurs when you do that. The energy savings --
well, as Don Doucette's post pointed out, that's moot.
