Hi, I recently bought a Mac mini to run Pro Tools subscription (specs in my user profile) I'm having a hard time deciding if I need to buy external drive to dedicate to audio. I've seen posts that suggest the system drive in the Mac mini can be used however, Avid knowledge base still says "One or more hard disk drives dedicated for audio record and playback"
I believe I want to purchase a fast SSD external Thunderbolt 3 to use as a dedicated audio drive such as G-Technology 1TB G-DRIVE mobile Pro Thunderbolt 3 External SSD. My old system used a dedicated 500gb Lacie Firewire.
AND a 2nd Larger capacity external drive to use for Time Machine backups of both the Audio drive and System drive of the Mac mini (2TB with 1.5TB free) like the G-Technology G-DRIVE USB 3.0 10TB External Hard Drive (0G05016). Does this seem like a sound way to spend the money to optimize my system for performance and backup? I just upgraded from Pro Tools 10 on a 2011 MacBook Pro so please forgive my ignorance of these newer technologies. Thank you.
