For CF, read is always faster than write! Read speed is probably
limited by the ATA PIO mode 4 or about 16.7 MB/s (burst!). Some
may even have the multiword UDMA mode 2 or about 33 MB/s, but
they are error-prone. And most DSLR don't even know how to take
advantages. I think the Nikon D2X may be the only one knowing
about the UDMA mode 2, currently.
For fast transfers from CF to disk/computer, just use a USB 2.0
card reader.
