I know that there are many types of cf cards onthe market. Is there any advantage to going with the monster speed cards? Can the NZ use this speed? Also, does it take more juice?

Thanks for any insight in advance...

For most applications - no.

Search the archives, a lot has been discussed before, eg:

Speed of CF compared to MS storage can vary a lot by manufacturer and batch (the flash chips can come from different manufacturers, regardless of what it says on the outer label)

If you truely need the speed, I recommend a 'fast' CF card (40X times or faster, I like the PQI brand myself)

HOWEVER, for most uses, you probably won't notice the difference. Running apps from the memory stick isn't impacted much by media speed (the app is copyied from the media, then run in the PDA's RAM).

My general advice is to not bother with the CF if you only need 128 or 256MB of storage space. The hassles and limitations of CF are not worth it for the small price difference IMHO.

You will see much more difference in write speed than read speed.

Power consumption also varies a little depending on CF card, and it is not always directly related to speed.

Thanks for the information. My intended use for the nz was as a part time photo archive of my pictures. I have 5 mp sony and would like store the photos on the NZ. If my camera supported the memory stick pro it would be a no brainer...but, alas, it doesn't. So, since I have to carry a PDA...and sometimes a camera...I thought the large, fast CF would work well for my application.
