If I have two hard drives on one ribbon (master/slave), or use two ribbons (two masters)?

Does it matter?

Thanks =]

It doesn't matter if you're only accessing one at a time;  but you'll get better overall performance if each drive is on its own IDE channel (i.e. two ribbons, two Masters).

... and as I implied, if you're accessing them both at the same time (copying data from one to the other, etc.) it will be appreciably faster if they are on independent IDE channels.

If you're worried about performance this much.  Forget ATA altogether and look at SCSI.

If you share two drives on one ribbon (master/slave), you are basically controlling two drives with ONE drive controller.

If you connect each to a separate port (master / master), using two ribbon cables, you are therefore controlling each drive with its OWN controller.   This is certainly the higher-performing setup.

Note: as mentioned above, the drive access time will only be improved when you're doing stuff that accesses both drives at the same time.    Meaning:  Two drives on a master/slave ribbon cable.   One drive idle, the second drive busy.   That "busy" drive will perform the same as one hooked to its own controller.
