If I remember correct the highest throughput of IDE is 133 Mbps so both USB and FireWire will easily work as an IDE converter. Although FireWire is less software dependent and more hardware dependent so you are usually much closer to it's max speed than with USB 2.0.

About USB bandwidth being a concern, it all depends on your motherboard or USB card. Some times all the USB ports on the motherboard are their own port but usually they have two USB ports that get split amongst the rest.

There's ATA133 which is 133 Megabytes per second. Beware the MB (megabytes) and Mb (megabits) difference being 8 bits to the byte. So basically Firewire 800 is 100 Megabytes per second and USB 2.0 at 480 Mb/s is 60 MB/s and Firewire at 400Mb/s is 50MB/s also there's USB 1.0 (1.1?) at 12Mb/s which is 1.5MB/s . A bunch of numbers.. anyway it is generally true that Firewire isn't as CPU intensive as USB 2 is. And also about ports and channels are true as well, meaning that although our computer may have 4 USB 2.0 ports they may all be on the same channel meaning that the 480Mb/s is shared between the 4 ports. However this doesn't mean that each port only has 120Mb/s .
Also an external USB 2.0 or Firewire CD/DVD drive you'd buy would simply have an IDE to firewire or IDE to USB bridge in it. There really aren't any "native" USB or Firewire drives.
I hope this helped clear things up. Any corrections are welcome. :-)

Thanks for the correction, that's why I put the if I remember correct, couldn't remember if IDE was measured in bits or bytes.

My pleasure

Ah very clear - thanks...

Is there an IDE to firewire cable. All I seem to find are enclosures?

So using a DVD on firewire isn't better... This would save bandwidth for other things!!!
Video recording, soundcard etc... These on USB 2.0!!!

I don't know, I've never looked for one... just find a really cheap enclosure and tear that apart for the IDE to Firewire bridge or maybe not [that's always been my solution (in my head at least because it's inexpensive)]. I don't know check the prices, go for whatever is cheaper I'd say. Good luck.

The IDE to USB adapter cable I was going to order is the one mentioned in this thread.

cant get usb to ide converter to work, any ideas?

Don't think I'll bother!

So what are people using to have the DVD drive down the front and PC in the back of the car?

There have been mixed reports with IDE cables (80-pin).
The IDE to USB Drive I found seems to have caused the majority probs.

I've only found IDE to firewire enclosures that are more expensive...

BTW the Imoega USB external CDRW/DVD are huge!!

I honestly don't think you will run in to bandwidth problems. Maybe if you hooked up a bunch of HDDs to the same USB port but I imagine most people will be running one HDD. I would just assign one USB port to your HDD and the rest to the other, assuming that your motherboard only has two ports.

Finally yesterday i solved my "DVD in the Glovebox" problem. It gave me so much headaches. I was really frustrated about all the USB stuff. What i did was get a External Firewire DVD player and i finally could say goodbye to all the problems. So i need to run a USB Extension and a FireWire Extension to my glovebox for my TouchScreen and My DVD.

The main problem what i experienced with USB was initialization problems after reboot or hibernate etc.

Now i only need to find a SlimLine FireWire DVD Enclosure for in my glovebox. So if anyone has a spare MaPower MAP-KC51SC1G for sale please let me know.
