USB 2.0 and DVD burners: A good combination?

[WooDaddy]

Maybe someone can answer this for me before I waste money.

I currently have an external USB 2.0 harddrive and was thinking about putting my DVD burner (NEC-1100A) in a USB 2.0 case. I'm using up both of my USB ports, 1 for USB 1.0 devices and the other for 2.0, and if I were to put my burner on the USB 2.0 bus would I be able to keep my transfer rates up to prevent buffer underruns?

Basically, here's how I would set this up:

USB 2.0 bus

PC Host -> USB 2.0 hub -> 40GB harddrive
|--------> NEC ND-1100A DVD burner (4x)
|--------> iPod

My 40GB harddrive is where I keep my data to be burned so basically data will be going back and forth on the bus. Now I know it's not SCSI where the controller would be smart enough to keep the data on the bus and prevent it from going to the pc, so I'm expecting some sort of bottleneck.. hopefully, it's not too much.

Any suggestions, comments?

I can't make any guarantees but it shouldn't be a problem. I have a 120GB HD and a DVD burner both plugged into the same USB 2.0 hub and I've never had a problem. Though I'm not sure if I tried to burn data from that hard drive.

I asked a similar question recently here

Didn't get an exact answer, but it sounds like dvd burning may not be so good at anything above 4x.

I'd put the DVD burner in the PC and leave the hard drive external. The hard drive will create more heat, so keep it out of the PC where you want as little extra heat as possible. That should also prevent any transfer problems, having the burner attatched to an IDE controller rather than USB. Having it hooked up to the USB port will most likely raise your CPU utilization as well.
