Yes. In fact, you can test this by unplugging the data or power cable to a
drive while the server is running. I've done this with consumer sata drives
and, so far, not had a problem. The server stays up and running and disk access
is not interrupted. I can then plug in a new disk and add it to the gmirror and
the array rebuilds.

I've not tried this with gpt, so I can't comment there.
