Just to add, I have read that memory cards have an estimated lifespan of 10 years. So make sure you date the last use, and every five years or so, back up the data to another card. Just in case. You will likely collect a lot of higher capacity spares over the years. Right now I have about 10 outdated blanks. And 8 32 gb class 10's I picked up for crazy cheap, $20 each. I could shoot raw for the next 10 years on my 60d and not get enough photos to fill them all. Plus, if you know you are shooting stuff that will never exceed an 8 x 10, it is pointless to shoot in 18 mp mode. 5 is more than adequate if you plan to develop them. So that will get you even more mileage. Personally, I have an 16 mb SD card on it's 10th year now, and all the files are perfectly fine on it, so I think by a ten year lifespan, they mean 10 years of normal writing/deleting/rewriting use.
What I am waiting for however, is a way to have the best pics, transferred from the cards to negatives, as negatives stored properly, are good for a century or more. Anyone know who does this?
