The maximum I get with RAID is 80MB/s. That is reading.
Since this is 640Megabit (Mb), I think you confuse GB and Gb
here. The first is Byte, the second ist bit.
However you cannot get even a Gb over standard PCI, so this
is no ordinary hardware. With 66MHz PCI the Gigabit might be
reachable. From my experience on Linux you can expect about
20-30MB/sec (= 160-240Mb/sec) on a drive to drive copy in a well
configured system.
There is a reason DOS is used. Doing this kind of thing with
a opaque OS like Windows is risky.

I've just installed a pair of Hitachi 80GB SATA drives in my PC on the
on-board SI RAID controller set up as non-RAID with XP Pro SP2. I get
transfer rates of ~850Mb/min (DI5 or DI2002) with my new Asus A7N8X-E deluxe
(all partitions are NTFS).
This m/b replaced my damaged Asus A7V266-E. I used to get fairly slow
transfer rates on this board until I edited the default.vdf file by
extracting the autoexec.bat file using the PQVF Editor then changing the
line near the bottom from:
PQDI
to
PQDI /ide=ON
then reinjecting the autoexec.bat back into the default.vdf file. The same
can be done for the quick definition files which also have the vdf
extension. This extra switch forces some m/bs to use ATA transfer instead of
PIO mode under DOS when running DI. This more than doubled the rate for me.
My new board doesn't appear to need this extra line so YMMV. The same can be
done for the DOS floppy. I got this tip from this NG a long while ago so I
apologise if this is old news.
I'm not sure about DI2002 but updating DI5 to DI5.01 /didn't/ update the
Rescueme folder which I copied manually. PQ may have address this later
having been told about it. I can't run either v5 or v2002 from Windows at
the moment but that's for another thread.
