three items here:
1.) at full resolution the Minolta (@5400ppi and true 16 bit per 
channel color depth)  is going to be creating larger data files than 
the Canon FS4000.
2.) Firewire and USB 2.0 are much, much faster than regular USB, which 
I assume you were using. USB 2.0 maybe faster than firewire depending 
on the implementation.
3.) ICE will slow you down.

What color space (workspace) are you using? Is your monitor accurately 
calibrated and profiled?

Thys,

  Thanks for this first look. I think in general you are going to b 
helped by more RAM and switching from USB to USB 2.0 or Firewire. what 
would really like to see is a Firewire 800 implementation as it is a 2x 
faster standard than Firewire or USB 2.0
