I currently have a DroboPro with 2-4TB drives and 6-2TB drives. The Drobo is connected to my IMAC 27 by ISCCI. My IMAC is also Thunderbolt capable also, but the Drobo is not and I was considering buying the 8TB G-Tech unit with Thunderbolt, and running it as my live editing platform in RAID 1 mode.. Can I run both drives on the IMAC simultaneously? Will FCP just draw from wherever the content is and how much will that increase my speed in editing or degrade it overall? Does anyone have experience editing with this platform?
