I loved Brook Willard's "Understanding the Mysterium". I was wondering if he was going to post anything with respect to the digital media options. I come from a film background and would like more information on the various features of each so I can better evaluate and determine which ones are right for my applications. For example how much recording time would I get a 4k on the 320 gig drive vs. say the 64 gig Red Ram. And what exactly are the Express Card/34 read/write module or compactFlash read/write module or the 1.8" SATA read/write module. Or is the RAW port the way to go. Thanks for reading.
