I have a DP 1.25 G4 FW800 system w/2GB RAM, Superdrive, and the original 120GB HD. I want to get set up for multiple editing projects and I would like input on the best strategies for HD configurations. I have two additional FW800 cards yielding a system total of three FW800 buses installed, so I could use external FW800 drives in a RAID 0 config, each with its own dedicated bus. That is one idea I like, because I could swap out drives and edit different projects back and forth with no backup/reloading issues (maybe using a Wiebetech BayDock 800 dual system with removable drives, each drive on its own separate bus). I could also use the raw HHDs themselves as my archival storage medium--revisiting a project for a client as easy as slapping the caddied drives back into the FW800 housing. The other nice thing about this idea is that with a FW800 CardBus adapter I could use the same drives on my Pismo in a pinch (Yes, it would be a slower RAID daisied on one bus, but see Barefeats.com regarding the speed of FW800 drives daisy chained through the Lacie CardBus unit--very respectable). Oh, and before I were to do that I would bring the Pismo up to 900mhz via the Powerlogix upgrade (already maxed out the RAM @ 1GB). The downside to this idea is that it is a LOT more expensive than just jamming my tower with drives. If I decide to just install three more drives in my tower, just how hard is that? Is it something I could do easily enough if I were swapping out drives for different projects? I am no hardware genius, but I am not afraid to do it myself if I have some good instruction. If anyone has install tips or animation links, please post them here for me. When asking this in the past people have told me that it is a hassle to swap out drives--not something you want to do on a frequent basis. For speed's sake, if I went the tower only route, should I get three larger drives (say 200GB each) and stripe them all @ RAID 0 via OSX for maximum throughput? Discuss. And thanks for you insights.
