I've been backed into a corner. The only solution is to buy stuff. My 2006 MacBook Pro was choking (multiple re-sets per day) under the weight of my recent upgrade to Lion. iMovie was a little slow before but now requires slow-clicking for even the most basic activity. As well, its 512 GB SSD was at 400gig and climbing with every video project. My 3TB Western Digital FireWire 800 external hard drive is stuffed with digitized home movies from the 60s and 70s, various video formats from the 1980s and 1990s. And some higher def stuff from the last fifteen years. It no longer will accept more data. And… my Airport Extreme is of the N-variety and is several years old. I might replace it with an ASUS. Not sure. So, after a couple weeks of internet research I figured out what I think I need for my basic AZRickD YouTube videos and photography. I don't game -- at all. I clicked the Buy button on the following 27" i7 iMac (plus Apple Care). And, I'll bump the RAM to, maybe 32gig, eventually. http://www.apple.com/shop/product/G...uad-core-intel-core-i7-with-retina-5k-display What I need now is advice on external storage (Thunderbolt, if possible). It essentially has to store my 3TB of raw video with enough extra space to serve as a RAID 1 (mirrored). Apparently I'll need some cables to go from FireWire800 to TB2. Maybe a double 4TB WD or OWC. Double 6TB? Others have suggested a single drive augmented with cloud storage (Crash Plan). I might go cloud. But not very soon. Thanks for the help.
