Hi everybody, I’ve pulled the trigger and have ordered a new 27” iMac / i5 / 580 / 512SSD / 8GB (+32GB upgrade). I’m currently using a 2010 27” iMac / 2TB HDD with a few external Lacie HDDs all currently utilizing Firewire but also have USB 2.0. I also have a Apogee Duet Firewire daisy-chained as well.. but that’s a whole other issue. I’ve been reading all the great advice over the last couple weeks about TB3 vs. USB3.1 but I’m wondering the best strategy for migrating to my new iMac with a much smaller internal SSD + the need for external SSDs for data and Time Machine backup. I’m completely on board with moving photos (516GB) and music (250GB) to an external SSD but capacity/budget may become an issue if each of those essentially need their own SSD (ie. Samsung 850 EVO SSD). What’s the optimal setup with the my new iMac best utilizing internal 512GB SSD, 2 TB/USB-C ports for large libraries of photos, music, video, data and also setting up a separate drive for backup? I assume an SSD isn’t necessary for backup drive? How do I best divvy up all my data and minimize the number of external drives required. I’m not sure what the typical setup looks like these days. I’m coming from a really old system so the new system is going to seem incredibly fast but I want to set things up that will last for a few years. Any suggestions are very much appreciated! Thanks.
