I am finally getting around to replacing my old HP MediaSmart Server which I've used for probably 15 years backing up the PCs in my house and as a file server. It has worked great but it is time to upgrade. I've ordered and am awaiting delivery of the DS920+ in late March/early April. I am a NOOB as far as the Synology hardware goes. What do you wish you knew about your systems before you purchased/installed it? What should I watch our for? I'm looking forward to learning from this group. Thanks.
