What you are describing is true for the Sparc 5 & 20. While the 4 used 
the same case, they mounted the drive over the motherboard on a bracket 
mounted on stand-offs. The drive connects to an 80 pin SCA connector on 
the mb via a short SCA-SCA cable. It is possible to mount the SCA 
backplane from an 5 or 20 into the 4 and then connect up 2 drives as 
they are in the 5 or 20. I've done this several times myself. It would 
be really nice if you could then use the 4's stock mounting location to 
mount an additional drive, but unfortunately both that drive as well as 
the lower drive on the SCSI backplane are both hardwired to ID3, so 
it's an either / or proposition.
