Choosing Storage Media
When deciding where to keep your data, remember that everything rots, and everything breaks down. It's the way the universe works, and there's not much we can do to stop it. Therefore, you have to think about your data's lifetime in terms of months, years, or decades.
Very little data most people have truly needs decades of preservation, but often, it doesn't hurt to have it around as long as possible. A minor amount of effort will help mitigate that. Specifically, expect to renew/refresh your data storage every 3 years or so - anything you don't do this with will progressively be subject to bit rot, moisture and heat damage, and being shoved into progressively unpleasant locations at home and office before someone decides it's trash.
