ASK NC

Hi, I would like to replace my old Netgear Readynas NV +. I need a NAS for photo files and audio files. I will use a SONOS system for listening. I want to be able to use the NAS while I am traveling in my Motorhome so I think SSD is the way to go as HDD will not handle the bumps and vibrations. I dont really need it for video, but if PLEX would be useful for my 1TB music collection I would consider that. I think a 4 bay would be best, but maybe a 2 bay would be sufficient? What NAS would you recommend? Also, if you could recommend a SSD as well. I have looked at the compatibility lists for QNAP and Synology and there are so many drives I dont know how to choose.

Thank you,
Jim
