Having bought a 15" Powerbook G4 (the latest, current model) a couple of weeks ago I'm now trying to figure out what I need for editing my (mini-DV) home videos. The plan is to start off with iMovie, then upgrade to Final cut express if I find out I need more. As for storage I'm going for an external Firewire drive and have already bought the enclosure (an OWC Mercury Elite Al) which has all 4 connections available (Firewire 400, 800, USB 1.1 and 2.0). I plan to hook it up to the Powerbook via Firewire 800, then use the Firewire 400 connector for the camcorder. The question now is: which drive mechanism should I buy and how much space do I need? Being concerned with drive noise I've been told that Seagate's Barracuda series used to be the ones to go for, but no longer. Samsung is apparently the leader in that direction. Their biggest (ATA) drives however are "only" at 400 Gbytes (Samsung HD400LD), and apparently not released yet. Any views or comments on this? I've got quite a lot of holiday videos to edit, and will also be using the same drive for audio (Logic express, Cubase, Garageband etc.) as a virtual recording studio, but nothing professional. Just for home/hobby use for now. So, being a newbie in this, how does a 400 GB drive sound, given what I'll be using it for? Is it a lot of space? Could I do well with an even smaller drive, or is even 400 GB not enough? Other brands such as Seagate have 500 GB drives available, but the noise issue is important to me.
