Back in 2005-2006, I made a few firewalls using 1GB SD cards.  They all lasted 4 years running smoothwall with continuous logging.

If you want to make it last longer, put /var/log and /tmp in RAM using tmpfs, then periodically (once/day), make backups of the tmpfs and store it on the SD card.  I then altered init to create the tmpfs, copy the files from SD card to tmpfs.  It worked fine until init was updated by yum.  Oops :)

Still true last time I checked but they use a lot of techniques to mitigate the problem.  They write to different locations and I'm told some have far more memory space internally than is available to decrease the amount of writes to any given address.   My first USB drives lasted maybe a year at most but I have a few now that are 7 years or older.

I remember that USB drives used to be good for a limited amount of writes. Is that still true?
