[G4] SCSI RAID for dummies?

[Marc Maderi]

To answer the original questions:

As long as you plan to use software raid then you do not need the "raid card".
I use for my raids FWB software raid (even if not the fastest and not 
yet OS X compatible, but at the time of choice it was the best option 
for me...)

Regarding cabling and terminaisons: yes you need the appropriate 
cabling with ACTIVE terminators.
The lenght is and number of connector depands on how many HD you plan 
to put in your case... Remember that the longest the cable the more 
stuff you will have to have to fit into your computer case and the 
moire stuff you have the less air flow you can get...
I have my self 2 seagate inside the case with 2 5 connectors + 
terminator U160 ribbon cable. I used "gaffer" tape  arround the 
ribbon cables to prevent them from melting.
I had such a ribbon cable melt inside the case and I had to replace it...

For the best performances a dual channel card is the best option, 
then connect each HD according to your raid set up. For a raid 0 with 
2 drive = 1 HD per channel.
By doing so I get over 90 MB/s with only 2 HDs.
