I have had a beast of a 2009 1TB 27 inch iMac, which is dying a slow death. My problem is every new Mac I see has SSD up too 512GB. My question and problem. I have 1.86TB of music, movies, TV shows and photos. If I move to a new preferably portable Mac. What do I do with my data? I do not want external drives... IF I have to have one, are the any and are they affordable or they all USB-C. Any advice in this matter would be appreciated.
