I’ve got a bunch of high capacity SD cards that i converted into little storage drives. I throw movies and tv shows I download onto them and it’s great for handing off to a friend or throwing into a device real quick.

I got these individual usb SD card readers but they get really hot if you leave them on all the time. So it’s nice to only turn it on when I need to read or write to them. The added security benefit is that when they are off you literally can’t hack them.
