> I've relocated internationally a dozen times, so a NAS doesn't work for me.

Same here.

I used to use 2x Seagate portable 5TB. Would mirror one to the other every week.

Now I use a Western Digital MyBook 20TB in RAID 1, and backup this weekly to my portable externals using Carbon Copy Cloner for macOS (ideally I would have an identical second one for this).

And run Backblaze for offsite backup.

I avoided a NAS because I prefer the speed of USB3 versus network - super quick to view RAW and video, and for ease of relocation.

I also have a 1TB portable SSD for my Apple Photos syncing iPhone content without filling up my MacBook disk.

The WD MyBook's are a bit dodgy though, there are so many horror stories. They encrypt all data, so if your RAID config is corrupted...which is supposedly stored on the hard disk, then you are screwed. Also, when you tell it to sleep when inactive, whenever you open a file dialog, the laptop freezes for 5/10s while it wakes up. There is also a bug in the utility application that says "can't access drive" which makes you think your drive is broken but it's actually just a software bug. Not running the utility software fixes it. I also think it can cause some unable to sleep issues for macOS. Sometimes it is super loud too, and its quite noisy.
