I keep a USBC thumb drive in the trunk of the car. It contains my password database and 2fa codes. These files are to get into my Proton Drive where I have anything important backed up.

I carry my late son’s school thumb drive (it is metal and has a hole for a keychain), and it has a copy of the last video I ever took of him (6 days before his death), his last school picture, and his last voicemail to me.

I’ve got one of those metal Samsung keychain USB sticks I loaded up with an assortment of tools from Portable Apps.

When I did much more general tech support for whoever asked, I carried a Live USB drive to boot from. I don’t offer that out anymore though, so no longer carry it. The closest to something digital would be my yubikey, and thats only EDC because its in my wallet

I used to carry one, but I never used it, so no.

I occasionally use local sharing apps on my phone, so maybe that’s considered digital storage?

Small metal memorystick of 256GB, with a usb-a and usb-c connector.

Can be plugged in nearly everywhere, even use it in my phone.

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.

I have a small pouch with thumb drives. One has tails, the others have files with various media on them. That plus an otg cable means I can have most of what I might want on hand in a pinch.

I rarely use any of it, but my bag has plenty of space, and the stuff is light.

But that’s my main bag, I don’t carry anything like that in-pocket.

Usually just my phone.
