Installing two hard drives

Hey all,

I'm just about to upgrade my pc once again, and this time I bought a brand spanking WD 80gb hard drive to go along with my existing 40gb IBM.

My question is this, when I go to install the new 80gb as my primary master drive, should I set my second drive to primary slave or secondary master, I have one CD/RW already set as secondary slave.

help is much appreciated.

 
I'll go with both hard drives on primary channel, and CDROM alone (the reason is that IDE is single-command interface, and if you have a bad CD, the hard drive on the CDROM's channel will just wait for the CDROM to complete his operations. Also I know (but I could be wrong) that every channel select it's mode of operation. And maybe the CDROM you have is not UDMA but PIO mode, and in this case the performance of the other hard drive will go down and processor load will go up.

It depends on whether you will be copying CD's "on the fly" and need that bandwidth or whether you will want to have the two hdd's on seperate channels to maximize the bandwidth that way. How will you be using it the most?
 
Since only one command can be outstanding on an ATA channel, if you put the harddisk on the channel with the CD-ROM, it'll wait for the CD to do its business before moving on. CDs are really incredibly slow; you have better performance having to harddrives waiting on one another.
