This is probably a dumb question, but if I use a NAS to store my MP3 files, what's the benefit of using an iTunes server on the NAS to make the MP3s visible as a shared music library for my Macs vs. just setting iTunes on my Macs to use a folder on the NAS as the main iTunes music library?
For instance, I've got all my video files on a NAS, and I've set up Boxee on my iMac and my MacBook (and on a Boxee Box) to scan the video folders on the NAS via SMB - Boxee finds and plays the videos fine, without having to turn on the DLNA media/video server on the NAS. I'm wondering if I can do something similar in regards to having iTunes scan in music from a shared NAS folder without using an iTunes server, and what the negatives/positives would be.
The reason I ask is that with my current NAS (an old Buffalo Linkstation) the iTunes server caused the NAS to constantly spin, creating a lot of noise; and it seemed tougher to manage/sort/update/tag the shared files via iTunes compared to having the library on the local disk. And trying to use the NAS to just store music files caused problems too - iTunes took a long time to load up the files when the NAS's iTunes server was turned off (I've got over 20,000 MP3s). (With the iTunes DLNA server turned off the NAS performed much better overall, with the key exception being the speed at which iTunes would load up the music on my Macs after any reboot.)
So I moved all of music back to the internal drive on my iMac.
But I'm thinking about upgrading to a new NAS (likely the Synology DS211j) - and I'm wondering if I should try this experiment all over again, or if I should just stick to using the iMac's internal drive (or a connected USB HDD) for storing, managing, and sharing my music.
I like the idea of the keeping all of my music on a NAS so I can access it from either of my computers (and Boxee Box) even when one of the computers is turned off. And, like I said, this works great for my video files (which I don't use iTunes to manage) - but trying to get this working for music files with iTunes has been such a headache, I figure I'm doing something wrong.
