A fellow I know, but never met. He's got two computers.
Desktop running XP, and laptop running Vista. He wants to
copy a couple gb of files, from one to the other.

So far, he's been copying some with a flash drive, and dump
them onto the other computer. It's taking a long time.

Suppose he takes a USB cable, from one computer to the
other. Would each computer show up as another drive, to the
other? Use windows explorer to click and drag and drop? Send
the data through the USB cable.

And what if one of the computers was turned off? Would the
USB cable provide enough power to spin the other drive, and
allow the data transfer?

Is he using USB-1 or USB-2.

I have an XP system and I replaced the USB-1 card with a USB-2 card and the
speed of the USB drive is very much faster. I would guess it is close to the
speed of my hard drive.

You would guess wrong...

Wow! Sight unseen and you know more about my system than I do? Amazing!

He doesn't have to know more about your system if he knows more about
transfer rates.

USB-2 theoretical maximum bandwidth is 480Mbit/s. In the real world,
counting system overhead, packet information, and the like, the actual
transfer rate is about 25-60MByte/s for USB-2.

Your ordinary SATA hard drive (bandwidth of 3Gbit/s) will move data at
around 300MByte/s - about 50 times faster.

Here's a comparison chart (scroll down):

I don't have to see your system to know that the hard drive is faster than the
USB interface.

He's right. Unless of course, your computer was built in 1982 and the
hard drive is an MFM or RLL type.

But if that's the case, it won't have any USB interfaces...

Simply no clue. The drives, he got off the internet, I'm
guessing.
