Same story here. I upgraded from a 12 year old JB7 (which had run out of disk space) to a 2TB B2 a few months ago. It's a real step up, and I'm really pleased with it, but I learned a few lessons on the way:
- Backing up the JB7 took 5 days, and still hadn't finished when we had a power cut, so I gave up. Fortunately I had an external HD back up, so I copied that in manageable chunks to a 250GB FAT32 drive, and imported the files from that. Took about 24 hours to migrate 7,000 albums
- If you have an external HD, it's worth spending time organising files on this before importing anything to the B2. The B2 organises files as artist/album, and my HD was organised only by album, so I had to create new folders for each artist, and move the albums into each artist folder (otherwise I was ending up with lots of "unknown" artists).
- CDs originally ripped on the JB7 didn't have track numbers. When those albums were copied to the B2 the tracks appeared (and played) in alphabetical order. I used Mp3tag to add missing track numbers to every filename before importing those albums to the B2.
- The wi-fi signal (even with the router in the next room) was far too weak, and trying to use the Web UI was either very slow or kept dropping the connection altogether. I was hesitant about dismantling an expensive brand new bit of
kit, but it seemed easy enough to do, so I took the back off and fitted an ethernet cable wired into a TP-Link powerline unit, with another powerline unit wired to the router. Works perfectly all the time, and scrolling through 2,000 artists on the Web UI is seamless.
I've also added a few hundred albums (all FLAC) since, and still have just over 1TB free, so plenty of space left to expand.
