Would that be "1 to 15"?

Well as much as anything else there's just the practicalities of chaining
them together in a way that's physically secure enough so that if someone
sneezes in the room then they don't fall apart.

No - 1 PCI slot for the 4 SATA channel controller, 1 PCI slot for the 4 x
SATA to External multilane adapter and another 1 or two slots for the
cables
to sprout sideways out of the adapter as you won't be able to use right
angle SATA cables on that adapter.

I don't think it can do both at the same time and handle 20 drives...

Yep but you can bet they won't be cheap. ;-)
I'm just looking at alternatives at the moment ...
... another possibility (and quite a reasonable costing one) would be three
PCI Belkin 5 port USB 2.0 cards and a dozen of these:
