Recommended by PB Tech as a solution for my small business backup strategy, which includes backing up all my cloud services and creating secondary Time Machine folders. I'm generally very happy with this NAS. It is quiet and incredibly versatile. Some of the setup is quite daunting for non-IT people, but the software and online support and documentation is very well set up. This one will hopefully be a central part of our small business for a long time to come, and I can see us expanding the Synology NAS 'family' in due course.
