Q: Very cool piece on USB
memory drive uses. I've wondered how to move my page file to one or set up a
secondary memory on one. Good idea? Doable?
A: It's an interesting idea, but not particularly
practical. You can put a Windows XP paging file on a removable drive,
but I doubt you can put your only page file on a removable drive.
Even if you could, the performance would be extremely poor. USB 2.0 has a
maximum transfer rate of 480mbps or 60MBps. Anyone who has ever used a USB
2 flash drive knows they do not come even close to that speed. By
comparison, a typical IDE hard disk has a maximum transfer rate of 100 or
133MBps. To top it off, USB drives are not built for rapid memory reads
and writes, and they would wear out quickly (though quickly in this case might
be measured in months).
