Also, what’s the archive lifespan of a SD versus a properly stored DVD. No where near as permanent I’ll bet.

Optical formats aren't exactly permanent. Over time the surface pitting erodes or becomes unreadable, the read/write surface is extremely sensitive to everything from dust particulates to scratches, and the discs themselves can be easily bent or snapped.

Optical discs are great, but they do have their drawbacks. When Blu-Ray won its format war with HD-DVD, a lot of people speculated that Blu-Ray would be the last optical format. I'm starting to think they were right.

By the way, Flash storage lasts for the physical life of the card. As long as you don't break anything, or exceed the read/write lifecycle of the Flash chip, the data will be there whenever you need it.

Thanks for the info- something I had been wondering about.

I still remember the first floppy drive I ever saw-- 160k, or something like that, and exclaiming, "Wow! Kiss that cassette deck goodbye..."

What are the read/write life cycles for flash memory?
