[G4] motherboard vs. pci drive controller

[Harry Freeman]

Greetings ( + )!( + )

Your G4 platform should have two hard drive controllers, one is the 
plug-in controller card that is located in the last slot next to PCI 
slot "D" which should be the one that your hard drives that are located 
in the rear of the box. This card interfaces directly to the 100 Meg 
buss and gives you a 100 Megabit transfer of data.

Then there is another controller that is part of the mother-board which 
connects your SVD/DVR and perhaps a ZIP drive and it is connected to 
the 66 Meg. buss and provides a 66 Megabit transfer of data.

So if you add a Sonnet Tempo ATA 133 PCI controller card and use that 
as your main drive connection it would appear that you will gain a 33% 
increase in data, however since your main data buss only operates at 
100 Megs, you will not gain any increase in data transfer.

Therefore that only advantage that you will gain is the ability to add 
more drives, and you will loose a PCI slot that can be used for other 
things.

Best regards,

Harry
