I read the internal Arduino's (ATmega's?) EEPROM's lifetime is limited to about 10k writes.
I am planning to make a device, which will require to read-write EPROM more often (to remember every change of settings). Let's say it will be 50-100 times per hour. That's - in the optimistic variant - less than 10 days of life for the Arduino.
What should I use? Is "normal" EEPROM (like AT24C256) good for me, or maybe I should focus on some other type of NVM?
EDIT: of course I'd like it to be as cheap as possible :)
