After getting the 16+ megapixel
Canon EOS 1Ds Mark II,
I found 2Gb CompactFlash cards to be inadequate for my needs.
The SanDisk Ultra II 4GB CompactFlash Card is my solution - holding approximately 230 1DsII RAW images.
The SanDisk Ultra II 4GB CompactFlash Card is fast - though not quite as fast as
SanDisk's Extreme III CF Cards.
