If I'm not mistaken a Firewire External is a case with a bridge chip AND an IDE drive in it. Thus said, the FW cases, depending on chip can accomodate various speed IDE drives(ATA66, ATA 100, ATA133, SATA, etc) The limiting factor is the bus speed of the computer these things are plugged into, which is about 50 for a S900. So, both the Firewire card and IDE 133 cards would plug into the same PCI bus, right.The Cache size of your drive might be more of a limiting factor than the type-is it a 2 or 8MB cache on your drive?

   I am running an S900 with a G4/450 processor, 1 gig of ram, a firewire
400 card, usb 1 card, an ata66 ide card with an 80 gig hard drive
partitioned into 10/35/35.  I have been starting some digital video work the
last 6 months.  I have burned a couple of DVD's that were nearly full.  It
takes about 19 hours to compress and burn the info.  I thought maybe a large
firewire drive would work better and than the ide on the ata66 card.  I
posted this on the videohelp.com site.  Someone there said the firewire
drive would cause problems because it would be too slow.  They said I'd be
better off getting an ata133 card and a large ide drive.  I thought firewire
had a pretty fast transfer rate. Would an ide drive on a 133 card work
better than a firewire drive? Someone else suggested that I pick up a new
Mac Mini.  Now that was an idea, but after checking into it, you can't get a
Mini with a G5.  I don't really want to buy a G4 machine.
   I know that this old dinosaur will never really blaze through a DVD
rendering/burning, but I'd like to get it down to 10 to 12 hours.  What do
you guys think?  Would I be better off with the ide133 card?
