Why the broadcast industry prefers compact flash

Compact-Flash-Card-19Ever wonder why so many of our high end recorders use compact flash, while most consumer products use the popular SD cards that are so much smaller and less expensive?

Dan Montecalvo and Tom Duffy, both with Tascam (Broadcast Audio Products) sent me this brief explanation of why compact flash media is preferred by many (professional) manufacturers over the smaller and thinner SD cards.

"Much faster write speeds, easier data recovery in case of failure and the CF connector is rated for 10k+ insertions (SD is rated around 1k). The SD card has its connection metal area exposed (scratches/grime) where the CF connection area is enclosed and kinda self-cleaning. The SD connector in the device can lose its 'springiness' and wear-out (gotta replace the device)...with CF, you simply replace the card because the spring contact part is in the card - not the device. All these reasons and more is why CF is preferred in the broadcast industry."

That Says It All! Yes No   Hmm, guess that's also why they cost lot more than the SD cards.
