I am looking first, for how to read and write to the cards, but the ultimate goal is one I would perfer not to discuss at this time. It involves product development in an area I perceive as a possible competative market.

There are many such projects available, and there are also very good app notes available in many places. One I can recommend is the sandisc site.

Generally speaking CompactFlash is easier since they have their own logic to do wear leveling and also since newer models also are protected against powerfail during write operations etc.

Then, CompactFlash is available with storeage space up to 4GB where as SmartMedia is more restrictive. Since the former is produced in huge quantites prices are still competitive although they are more complex.

So, if you have the space on the PCB CF gives you more flexibility.

Use google and you also find a ton of information about the subject.
