Because:
DSE 20GB - $209

Seagate 500Gb - $399

Sorry PC,not made myself clear,

Why 209 for 20 and

399 for 500.

Seems out of kilter to me.

First one is using a portable hard drive - so very small and probably gets all its power from the USB bus.

Second one is using a desktop hard drive, much bigger physically and will not get all its power from the USB bus.

Portable technology is generally more expensive.

Cicero, just in case you plan to buy one at DSE:

Prices have come waaaay down!
e.g. 250 G for $110

I appreciate your help on this,thanks all.

Portability seems to be what separates,how would 500 be connected,not USB?

Yeah, the 500GB would be connected via USB but would also need to be plugged into the wall for power since it would be a regular 3.5" HDD. The smaller 2.5" notebook HDD's usually just get their power via USB (sometimes using two USB connectors to get this power), cutting out an extra bulky power cord. And of course, the notebook drives are smaller, almost pocket size. The 20GB you linked however is a smaller 1.8" drive so is definitely pocketsize.

How slow are external USB hd's? Time to backup 1 Gb?

My system does not have firewire which I believe is the fastest.

Yep.
But I'd buy the Seagate anyway instead of the who knows what dodgy brand is in the DSE one.

While USB2.0 is faster than firewire on paper ( 480 Mbps versus 400 Mbps ) its not in real world use - http://www.usb-ware.com/firewire-vs-usb.htm

You could use the theoretical speed to work out a "theoretical" transfer time for 1GB

Firewire has a faster sustained transfer rate. USB 2.0 has a burst speed of 480 mbps after that it drops of a lot.
Firewire also comes in 400 and 800mbps.

Just a word of warning: if you intend to use a portable usb drive as a backup drive, make sure you ALSO do backups on CD DVD as well.
Why you ask? Well I just had a 200gb Seagate Barracuda backup drive fail with all my backups on it...
It runs nicely - humms along just like it always did except its not detectable by the PC - not even the bios sees it if I take it out of the USB case and put it in the PC itself.
So I assume its a problem with the circuitry on the drive rather than a mechanical failure.
I've lost 160gb of backups - but it doesn't matter as I also have the stuff backed up on DVD :) :)
