One thing that really got me while working on computers and networking right as LAN networks became a thing in the late 90s and early 2K years was.... I'm connected to this switch, and so are they. Why do I need to burn a CD/use an external hard drive (later a flash drive), to move data?
Took me a while to figure out SMB/cifs, and when I did .... Game changer. Since then I've also learned all I can about storage, networking and file sharing. Most of my USB drives sit on my desk and don't get touched. I couldn't tell you what's on most of them. I've picked up a few thinking that I'll use it, but the most useful thing I've done with flash drives is to move data between computers when upgrading other people's computers. For me, I just make sure everything is backed up/synced to my local NAS, wipe the system and reinstall without a care in the world.
Its a CM3588 NAS board from friendly elec running openmedia vault Debian 11 with home-manager for nixpkgs.
I run nextcloud for backing up my phone storage every night. And have SMB share setup for all my laser cuting files!
Originally all my files for my business where running off a 4tb USB HDD which was starting to fail. And yes there was no backups. So after I made a little money selling my laser cut goods. Bought the CM3588 nas board with 2 one terabyte sata m.2 ssd's which are in raid 1 for redudancy. Also have a off site backup on the computer that runs the laser. And another tid bit all the computers I use are exclusively linux. The computer that runs the laser is zoron OS. My main rig runs nixos, my LAN gaming machine runs gentoo aswell as the laptop where I do most of the fianaces and designing. The laptop is a t440p which is librebooted and runs gentoo :D.
