I am using a viking 128 CF card in my Nikon 4500.  I notice it takes a while
between pictures (like 3 seconds).  Could this be because the card has not
been formatted specifically for the Nikon?  In other words, it works, but
poorly.  Of course I will format it in the camera (as soon as my battery
finishes charging), but I am curious if this is why it has been taking so
long to record pics.
