Hi, I need some information regarding USB2 Transfer rates. I have a Macbook Pro, 3 External Hard drives (all USB2) and an LG Ext. DVD Burner (USB2). They all plug into a D-Link USB Hub, that then plugs into one of the 2 USB ports on my MBP. The other USB port on the MBP is taken up by a keyboard (I run the computer lid-closed + ext monitor). Now, the reason I bought the External DVD Writer is because the Superdrive in the MBP is only a 4x, which is simply not good enough. So the 16x External drive is so I can burn a full 4.7GB DVD in around 5 minutes yeah? I ordered some Datawrite Titanium 16x DVD-R discs with the drive as well. I have only burnt one thing so far and i wasn't impressed. Majority of the DVD burning i will be doing will be from any of the external hard drives. The first burn I did with the new drive+disks took around 10minutes (burning a DVD Video TS folder in Toast). I was quite disapointed as i thought it would fly. I am hoping that it is not because the HDD's and the DVD Writer are both on USB2? Is it possible that i am saturating the bandwidth by reading from the USB HDD and writing that info to the USB2 DVDRW? When i was burning I had nothing else running that could tax the system? Ideas? (unfortunately I cannot tell in Toast what speed and how much data is actually flowing through at the time of writing - am looking for a burning app for MacOSX that shows me that).
