1D Mark IV memory question

<p>It is time for me to buy some memory for my 1D Mark IV. I always use the second memory card as a backup. I cannot find the Canon specification for write speeds to either the CF card or the SDHC card. Does anyone know what they are? Does the camera write to the cards in parallel? If the camera does write to the cards in parallel, my thinking would be to purchase cards with similar write speeds.<br>

Thanks,<br>

<p>I know the the 1D Mark IV can shoot up to 10.0 frames per second for up to 28 consecutive RAW files or 121 full-resolution JPEGs when using UDMA Mode 6 CF cards. If your looking for mid level cards they run about $68 on amazon, and those usually take care of most people. Writing in parrallel should be answered in you info book that came with the camera.<br>

Read the <a href="http://www.thebestcameraforphotography.com/canon-eos-1d-mark-iv-review.html">Canon 1D Mark IV Review</a> and that may help.</p>
