I wonder how similar/different those memory cells are to the structure of our CF and SD cards? We constantly write to, erase and format those little things, and the better ones are supposed to last for years.
They are very similar. CF cards have the same problem with limited read/erase cycles, and they use the same wear levelling technique to even out the wear. You'll sometimes read posts from people giving advice on how one should try to minimise that wear, but they're normally a load of old tosh. Here's why...
Most of the memory used for CF cards can handle something like 10,000 write/erase cycles. So a 16GB card can handle about 160TB before it starts to wear out. That's 160,000,000 megabytes. If each of your raw images is 25MB then you can write 64 million images to your card. If you shoot 1000 images per day, every day, then your card will wear out after about 175 years!
