Firewire card reader (SanDisk) - SanDisk 4GB Extreme IV (picture below):
Initially I couldn't see any difference between the Transcend card and the SanDisk card when I used the USB card reader. The difference between the two CF cards appears when I has used the fire wire card reader. It seems that a card reader can makes a difference. I have to note that there are definitely USB card reader, which can show the difference of this two CF cards.
