SanDisk Extreme 8GB CompactFlash Memory Card UDMA SDCFX-008G-X46 (Personal Computers)
Really excellent memory card. Fast, reliable. The've extensively used during an African safari (7,500 photos), with many gusts to 6 i / s, each of 5 Mb in jpg. Never had any memory overflow (I use a Canon EOS 40D housing).
