SanDisk 4 GB Extreme IV CompactFlash Card vs. SanDisk 4 GB Extreme III ?
What is the difference in between these CF cards besides the higher speed of data transferring of SanDisk 4 GB Extreme IV CompactFlash Card ? Is this difference crucial?
Thanks!
The difference is in UDMA technology. Not all DSLR’s are UDMA compliant though, so the difference is really nil. Like a dummy, I bought a 4GB Extreme lV CF card for my EOS 40D without first researching it. And the 40D is non-UDMA compliant, so the speed is really about the same at that of a Extreme lll, which is a lot cheaper. Hey, you live and you learn, right? Here is a short article on the features of the Extreme lV.
