Is 7200 rpm FW drive overkill if sharing one firewire port?
So I'm looking to do some DV capture with my pBook G4, but I need more storage. Faster drives are supposed to mean less dropped frames, but since my pBook only has one firewireport and I need both my camcorder and the external FW hard drive to share it I wonder if I will only get about half the bandwith anyway in which case a 5400 rpm drive would seem to be more than enough.
Actually, I have been quite surprised at how well my 4200 rpm internal pbook drive does at not dropping frames. It might be that iMovie is savy about buffering into ram (I've got half a gig of it).

That said, they're in separate ports, and I don't know how the controller would get on with having to squirt it all back and forth through the one port...

Could you please elaborate ?
I think every "not-too-old" 5400rpm drive can handle 4Mo/s sustained, no ?
A DV-stream should be 3.6Mo/s.
oh, hey, it looks like they made the decision for you: <a href="http://eshop.macsales.com/Catalog_Page.cfm?Parent=680&Title=FW&Template=1" target="_blank">see here</a>
However, I have to reiterate, I've never tried plugging the camera into the back of it and shunting all the DV through one Firewire port on my Mac.
I like those guys there, too. They will chat for an hour if you let them while you are ordering. They must treat their employees great for them to always be so happy.
