Well Paul, HDD throughput measurement using the same software gives 39-40
MB/s for primarily partition and 31-33 MB/s for secondary. I consider these
numbers to be fair enough to trust this software for measuring storage
devices throughput.
As about the system, I have 2x60GB Maxtor 7200rpm  ATA133 HDDs arranged in
RAID Mirrored array, running by Ahtlon XP 2100+ (1.733 GHz) in Win XP Pro.
Frankly, the same numbers I got previously in Win2K, although the storage
performance wasn't stable then, unlike in XP. (Occasionally after the USb2.0
storage device is plugged in, the OS recognized it as USB1.1 instead so the
real throughput was bellow 1 MB/s).
IN XP I never encountered this so far, although I use OS own USB2.0 driver
instead of the one came with the device.

Regards,
Alex Z

What sort of speed measurement do you get from the local IDE disk? That's
about what I get for my 7200rpm ATA/100 disk on my 1.4GHz Athlon system. It
may be that you're limited by the speed of the OS in doing file accesses.
The excess speed of USB2 may still be useful if you're running more than one
device at a time from different processes.
