I bought 16 GB Sandisk CF on November 2009, and restored
backups from a broken hard disk to the CF.
So this net4801 has full FreeBSD installation on the CF card.
I've been running this net4801 since then, non stop, updating FreeBSD
and installed ports when needed.
The system writes logs to /var filesystem, anywhere between
1 - 16 megabytes per day, usually more than 10MB per day.
The logs are rotated and compressed.
The total usage of the CF is quite low, it is below 7% at the moment.
By total usage I mean total sum of Used from df and swapinfo divided by
total sum of blocks shown by df and swapinfo.
The /var fs Capacity is 14% at the moment.
So my 0,02 euro advice is: buy a large CF and leave lots of free
space to the CF and to the filesystems.
