I can second that, from experience. I might add while I'm typing, I'm getting ready to update my backups. I just booted the NAS box. I hit the power button on the way to my chair. By the time I read your reply, it was already sitting at the login prompt. I think it boots a little faster. Having the OS on a SSD might be a little faster. While I like the new GPT way, I really need to use the old way on the older hardware. I just keep forgetting to. :/ Dale :-) :-)
