    USB2 is not faster than IDE, but it's pretty quick. Here is a report from Sandra on one of my HDs (a Hitachi Deskstar (IBM) 120GB 7200rpm 8MB cache).



    The red is my drive. Below it is what Sandra thinks a similar drive should do on ATA100. Below that is what Sandra thinks a similar drive should be running, if connected by USB2 (I'm not sure why I beat their estimated by a fair amount). Then you have USB1.1. And I threw in a SCSI for kicks.

    Also when I hooked the same drive to the same computer via IDE, I got around 33,000kB/s (just a little more than Sandra estimates).

    how do you power it in the car. do you just use the adpater to transfer the stuff, or as a whole, and use it in the car. since an invertor, woudl generate noise, and you would pick it up in the car

    I always thought about buying 3 or 4 USB-IDE adapters and make an external RAID for my laptop. In the US we can buy these for $20 so 3-4 isn't that bad.

    I use an inverter. There is a little background noise, but you can't even notice it when the music is playing. The external drive is powered by an adapter connected to the inverter.

    It's an AC to DC transformer......u get 5volts and the 12volt which is a normal molex adapter e.g red, black, black yellow (5v, gnd, gnd,12v)
    it's 5 volt that goes to the IDE connector and i jumped the molex connector from my opus...................... simple

    Ditto, my USB hub is powered off of my 5v rail (HDD rail) from my motherboard's PSU. It's nice because it turns it on/off with my PC.

    Many components like this only require 5v..

    When it says "self-powered" mode, does this mean it gets power off of the USB port and won't require the separate power plug? When WOULD you need to run separate power?

    Most of the time with USB stuff, this means that the device will draw power from the port. Not sure how this will come in to play with a drive. I know 3.5" drives need +5V & +12V. I'm planning on having to run a power line. If it will power the drive by itself that would be great but I can't give you a positive answer at the moment.
