I'm planning to get an iMac Pro for my office, and it will be loaded and used for some bigger projects by someone else on occasion when they are occasionally working at the office. Since it will sit unused most of the time, if I boot it to an external, portable SSD and have all my own personal software and storage and projects setup on that external SSD, I should be able to unplug that portable USB, take it home with me, plug it into my 2017 27" regular iMac 5K and catch up with some work, right? I realize I bottleneck the speed and loose a lot of the advantage of an iMac Pro while doing this, but if having my work be portable (98% of it is just on a word processor program, 2% is some 3D modeling software) and I enjoy using the larger 5K screen of an iMac over speed and power, this should in theory work, right? And if i have a second external hard drive, and use it as a Time Machine, I can take that with me as well, and have all my work backed up, regardless which computer I I'm using, if I plug both external SSD's in at each place? I'm just looking for someone to confirm I have it right before I splurge on a tiny new (but expensive) pair of Samsung T5 portable SSD's. A 2TB for my desktop and storage, and a 1TB to use as a time machine. Does my thinking sound correct to those in the know....?
