Nothing beats the convenience of unplugging a drive and plugging it to a next computer and it just works, within seconds you have everything ready for work.
Is there a good file system for this? For macOS I’d want APFS, for Linux ext4, Windows NTFS (maybe ReFS?). You can typically get read only access between them, and I know Linux can do RW with NTFS - but I’m not aware of a good option.
I'm living this right now. I just switched laptops with my partner as she's doing a bunch of video editing. So she got my Pro and I'm using her Air. (I know, I'm an amazing boyfriend.)
So yeah, great, I have all my files. But none of my apps! And I'm not signed in to any of my websites. And even if the apps I use were on this laptop I'm not licensed for them. Oh and I have to get my password manager before I can do any of this. And configure my email.
Conservatively, it takes a couple of hours to restore minimal state. I know, I just did it!
In that time I could have connected an Ethernet cable and copied all of my data between the two internal SSDs. :-)
Edit: oh yeah, and I just command-strip-attached the SanDisk SSD to the back of this laptop's monitor. Because otherwise when I go and work somewhere else I'm trailing this umbilical around with me. This setup is absurd and I hate it!
Edit2: oh yeah again, now this external drive is constantly occupying fully 50% of my USB ports. Terrific.
