Hello all. Let me start by apologizing for a new thread. Upon searching, it looks like there have been some answers to what I'm looking for, but all for different Macs. The closest I came was the "FCPX bottleneck question" thread, but that dealt more with speed. I'm not worried about speed right now, just storage. My iMac full specs are in my sig, but as far as space goes, I have a 500GB internal SSD. I recently did a friends wedding and importing files from 2 Canon HF21's they are all AVCHD (the files from the T2i are not as huge). I used the "optimized media" option and the project is now almost 200GB and my drive is full. What is my best option for external storage? With the iMac I am limited to USB 2.0 and FW 800. I have seen posts about getting a 2.5" or 3.5" internal HDD in an external enclosure for FW 800. With this comes options RPM for the drive, Bus powered vs. DC power, and whether to look to RAID or not. Can an external drive handle FCPX media storage, rendering, etc. with good results? Is it better to move all my local media (iPhoto, iTunes, etc.) to the external and just use my SSD for the boot and FCPX? So many questions and again I apologize if this has been addressed ad nauseam , but I am just getting started again in this field. I remember thinking I could never fill a 500GB HDD on a G4 or G5 yet here I am thinking, I need a few TB. Much appreciation to all.
