I have long hesitate to take on what Nas ... I even did a test with inconclusive MyCloud WD. For the final launch Synology me! And here .... TOP Responding, for now, in every way to my expectations. It is fresh, but already serves me: - Backup Time Machine - DLNA server for all TV - ITunes Server for all my chains Hifi - Outside access to all of my library (video, images, music) Coming soon: - Video Surveillance - Download manager (replacing Jdownloader) For now ... super happy.
Regarding the RAID (certainly very interesting), I pass me via replications tools with a USB HDD that I had. This manipulation is some little heavier, but the backup is located on a different physical media, which reassures me.
