I carry an external SSD Drive (5TB) with appx 3TB of music. Yes, I realize that is a lot more than I would ever need but I like having it all in one place (less the backup I keep on my NAS). Are there any limitations to the SC5000 in connecting an external HD? How much data can it read and will there be any latency issues? Serato doesn’t like it very much but is manageable. Just takes quite a bit of time (a couple seconds) to figure out what it wants to do when searching for a song. I have the most powerful Mac available but it doesn’t seem to matter much.
