Sorry for the drift, but . . .

The numbers quoted above aren't terribly fair to SCSI.  Even some extremely
inexpensive SCSI discs available now have burst rate capability of 1.5 Meg/sec
on the bus, although with lower average rates due to the mechanisms.  The
1.8 Meg figure for the Eagle sounds like a sustainable average rate if doing
a raw read, but going through a file system slows things down considerably.
