Many of these files were accumulated over the years, so there is work to be done. Many of these are Arabic releases and there are issues with the metadata. To add, given that I have many CDs too I am ripping them in WAV and MP3. I am looking for an all-in-one solution because I prefer to work on tagging and cleaning up my library, the original files on a regular basis. I read in the forums several comments on dealing with large libraries, I believe the support never recommended Macs I really appreciate it, I was planning to get an M1 mac mini but was really hesitant to take this decision And make sure to say away from connecting Core via WiFi, only Ethernet and it’s highly likely you will see gigantic improvement in speed and overall you Richard for the update

Therefore, my advice - get a standalone machine, be it Mac or any other stuff – get yourself either spacious internal SSD or index files to external HDD or SSD - can stick with Lacie if you wish, but Samsung makes a very decent yet affordable SSDs. In regards to the size of the library – among more than 250,000 Roon users there are dozens of users who have bigger library than yours and they utilize SSD, which costs a buck, for sure, yet they get what you pay for - search a forum, it’s highly popular topic. In numerous FAQ articles written by Roon it is said that RAID and NAS enclosure are highly not recommended as storage and you might experience delays because of that. The part which you previously skipped to mention is that it’s RAID. An not only on HDD but on a clunky 2big Dock - I’ve used it previously. Your internal storage might be SSD but you store your music on HDD.
