Hey, I have a 2017 iMac with 2tb fusion drive, and looking at using an external SSD to run the OSX/Apps etc off. My 2013 MacBook Pro is being replaced by Insurance, and they're sending me the 512gb SSD from it – would this work fine in a USB-C enclosure and used with the iMac? As for the 2tb fusion drive, can this be partitioned 50/50 then used as a backup and extra space drive? Or should I just use it as spare space? Will I notice much of a difference in speed? I have the 4.2Ghz model with 40GB ram.
