Writing that often to a flash card is both slow and can result in the CF card failing.
I'd suggest using a ramdisk and writing back to the flash at given intervals, say every 24 hours.
Not sure if this goes for a sandisk but on another platform I was on (using NAND flash) the driver itself spread the writes to all availiable sectors, giving a better life time of the flash.

Subject: [Soekris] Question about CF Cards
Hi, I've been looking into the Soekris 4501. I was wondering about the
CF card. I've read that some CF cards have say 1,000,000 writes. My
4501 system will have crontab, syslog-ng, sshd, and pflogd all logging
locally to the /var/log directory. Won't all this writing to disk be
bad for the CF card because of the number of writes, and make it not
last very long, since these programs will be logging things. The /var
paritition will be read/write. How will this affect the CF card, and
it's lifetime? I would like to hear what other people do? Let me know.
