Don't know about lasting 100 years since I don't believe I'll be able to check that..........

think usb sticks will likely be more reliable then optical media which can degrade over time and being a loosely fixed disc rotating at a very high speed the risk of burn errors are ever present.

I used to be in the polycarbonate business (Lexan). A lot of our PC went for CD & DVD production. It's pretty durable stuff (it's also what the NFL helmets are made of, and NHL face masks/visors too, not to mention NASA space suits & the canopy on fighter jets). But still, Rudegar has a point, spinning media seems to be on the way out. Will DVD drives still be around in 25 years? Maybe archive on both USB sticks & DVDs?

Or for that matter... How long will USB 2 or 3 be used? Or how long will software be able to read the current photo file formats? I guess it deppends on how long you want to keep them. I have photo DVDs that are perfectly readable after 25+ years. Maybe archive those photos in B&W and print them with the silver halide process. We know that'll last at least a couple hundred years.
