[citation][nom]applegetsmelaid[/nom]Hmmm. SD cards don't seem like a reliable way to store important data permanently. They are much more fragile than optical media. I would rather store my data on a BD-RE. Optical discs are water resistant and require a greater deal of force to physically damage than and SD card. I've seen SD cards fall apart just under normal usage circumstances; I have standard CD-R media that has withstood a great deal of abuse and they still work after a decade.[/citation]
I hope you are kidding. SD cards require far more force to break. On an optical disk all it takes for the data to be rendered unreadable is a good scratch. Sure it is fixable but it is a pain in the but.
Another bonus for SD card is that they don't take light damage. If disks are exposed to sunlight they will eventually stop working at all . Granted its a long term issue but it's one that SD cards outright don't have.
As for water resistance All you have to do is dry the thing out (just wait), or seal it, which is often done at the factory. you have to dry a CD before you put it in a disk player anyways.
Did you see the article on here about a year ago that showed the amount of damage a USB key could take before it would break. SD cards are even more durable than USB keys. They could do just about anything to them and still expect them to work.
Not saying that they will replace disks with them because the costs are simply prohibitive
