lifespan of current media
There is a finite lifespan for today's media and it varies from manufacturer to manufacturer. For dvd's there is no real standard, currently, for measuring lifespan across all manufacturers. So we'll look at the average. For dvd-r or dvd+r media its between 30 yrs and 100 yrs. with the 100 yrs probably being an outside, wildly optimistic number. One decent scratch on it and its data is damaged, probably lost forever to your posterity. A USB flash drive or a micro sd card are both good to consider. They are both electronic storage mediums with non volatile memory, meaning that a power source is not required for them to hold your data in memory. They are more durable than dvd media. A usb flash drive is larger than a micro sd card and therefore more durable, less likely to get lost. USB flash drives are capable of handling 10 thousand to 10 million write and erase operations during their lifetime, depending on the source as well as the specific USB drive. Regardless, a flash drive typically will outlast any standard hard drive. The main concerns about the life expectancy of a flash drive are damage from neglect and becoming lost or stolen. Insuring that future generations will be able to use the device you choose is another matter. The suggestion posted about including the equipment to read your media is a good one on the surface, but also consider that the more equipment you choose to store in your "attic" time capsule, the more probability it will become damaged or degraded over time. Unless there is some great technological disaster in the future, they will be able to read a USB drive in 100 or 150 yrs. If a disaster does happen, then storing photo's is your best bet. It worked for your family album for more than 150 yrs. Whatever you choose, keep it stored in an air/humidity free environment.
