I've been running a Powerbook entirely from a 16GB Sandisk CF card for a long time, with no ill effects yet, in fact it outlasted quite a few SD cards. There are a few things you can do to avoid unnecessary writes: - align your partitions to a largeish power-of-two value, like 16MB, hopefully the cards erase size will be a smaller power-of-two value so all filesystem blocks will be in exactly one CF block. - mount your filesystems with noatime and nodevmtime - put /tmp and /var/tmp in a tmpfs - make sure you've got enough RAM so you don't need/use swap space have fun Michael
