I don't know about buying a cable to chain an Apple 5 1/4" drive to an Apple
3 1/2" drive, but I do know about the daisychaining in general.
First, you won't need to buy anything if you have an APPLE 5 1/4" (as opposed
to an Apple UNIDISK 5 1/4") drive and an APPLE 3 1/2" drive. The 5 1/4"
should just plug in to the port on the back of the 3 1/2" drive. (IN THAT
ORDER - the first drive plugged in to the computer must be the 3 1/2".)
If this all goes well, the card in slot 6 can be removed. I know that programs
will still find your 5 1/4" as in being in "slot 6", but I don't know if you
can then put a different card in slot 6.
If all this didn't work (i.e. the plug on the 5 1/4" doesn't fit in the back
of the 3 1/2"), then I can't help you, since I don't know if that adaptor cable
exists.
As far as advantages, I don't see any advantage to changing your system over
unless you really want to put something else in slot 6. It's not faster or
anything like that. The only disadvantage to daisychaining is that the more
drives you have in a chain, like in excess of 4, you could run a problem with
getting power to the drive out at the end. Each drive takes some power, and
after 4 or 5, the last drive (or those past 4) may have power problems.
I hope this helps.

When you daisy-chain a 5 1/4" drive to a 3 1/2" drive into the Smartport, you can then use physical slot 6 for something else as long as it is not identified as a drive. You can not put another drive controller card in slot 6 under those conditions. But e.g. a Mockingboard is o.k., or an A/D converter card.
