Mother board compatibility and CF card usage as main storage device for small DNS server

[Kaya Saman]

Hi,

I'm planning on using FreeBSD 8.0 x64 RELEASE edition for a small 
primary/secondary DNS server setup.

The system will run Bind9 and have some zone files and views for the few 
people I host for.

I am considering using a dual Atom system board with 2GB RAM and for 
storage was thinking of going for 16GB compact flash card instead of a 
normal hard disk......

This is a bit radical for me as I have never used this kind of setup 
before so I'm not sure how suited it will be???

These are the system boards:

I mean for a DNS server (all be it a small one) is it wise to use 
compact flash as storage??

Thanks and regards,
