Wow Martin you certainly have researched the topic well!  Like most new technology I guess this will prove of more value in the future, though how they come up with such statistics for reliability is a mystery and who is going to be around in 342 years or the 112 or 80 years to say they got it wrong..

Rare for me to have a computer or HD longer than 3 years at best before it is so out of date to seemingly be worthless.. One thing for sure though that the Flash cards are reliable in the extreme and in time with the rate of progress we will be carrying all our data on them. But again I am sure this way well be old hat again in an even shorter time
