For me, it was getting a handle on rsync for a better method of updating backup drives. I was tired of pushing incremental changes manually, but I decided to do a bit of extra reading before making the leap. Learning about the -n option for testing prior to a sync has saved me more headaches than I’d care to enumerate. There’s a big difference between changing a handful of files and copying several TB of files into the wrong subfolder!
I carry a 2 TB Silicon Power drive on a keychain sometimes.
In addition to an encrypted partition for secure data transport, I keep a fat32 partition that can supplement phone media when I travel.
A few file formatting choices (mp3 or mp4 suffixes) mean that media playback usually works with tvs that I trust, too.
If I need more space, I can temporarily delete a few albums. No big deal.
