I'm looking for a generic word to describe (removable) computer storage such as CDs, USB sticks, floppies etc which is as clear as possible to non-technical people. It doesn't have to clearly distinguish removable from fixed. "Media" and "storage" are both candidates, but I am not sure how natural they sound to the average person. "Disks" is my current choice, but using it for USB sticks seems to me to be stretching it slightly.
My two suggestions would be:
- Peripheral storage
- Removable media
No matter what term you use, though, I'd recommend providing a either formal definition, or a parenthetical for example list. Don't assume everyone will automatically interpret the term in the same way. As technology evolves, it becomes more and more difficult to coin a brief term and have it universally recognized, with no potential for ambiguity or misinterpretation. The terms above could be used to describe an antiquated floppy disk, a CD, a DVD-RW, a USB memory stick, a flash card, a SIM card, or a 250 GB portable hard drive. For that matter, a digital camera, an .mp3 player, or even a cell phone could be used for portable digital storage.
