After filling my brand new 750GB iMac up with home videos and my ripped DVD collection, I am looking for a viable storage solution, as I am sure many of you are too. The way I see it, the more popular DVD ripping and home movie editing become, the more people are going to be having th is problem. My question to you is this: What is the best solution for the average mac user who needs considerable external storage, which is expandable for the future and has the capability to back itself up? I've done a BIT of research on RAID, and have familiarized myself with the basics. I have also seen a few videos on the drobo, which seems to get great reviews everywhere. But, I want your opinion. For everyone with an ever-expanding iTunes library and iMovie folder that will be searching this very topic... what is your advice? What rules-of-thumb should we follow? Which 'traps' should we look out for? Can the average consumer handle running a RAID array? Thanks for your input!
