I have a IIsi which was purchased with a dealer installed 100 Mb Quantum
hard disk drive in place of the Apple supplied hard disk.  The first
thing I noticed was that the time to duplicate a disk file seemed
much longer than my old SE/30 with an Apple supplied 80 Mb drive.  For
example, it take about 30 seconds to duplicate the MS Word application
(about 680K) on the si.  At work on a 20 Mb Bernoulli disk, a IIcx will
duplicate the file in 5 seconds and an SE will do it in 10 seconds.
The time is not appreciably affected by the color
vs. B&W mode on the si.  Note that recent speed tests reported on
the net have been for computation speed and not disk I/O.

does anyone have any ideas on what makes it so slow?  would partitioning the
disk help?  Has anyone times this on the Apple 80 Mb disk?

Thanks,
Disk Kalagher
