32GB SSD: optimal artitiion setup for multiple OS install from 630/190 through QS?

[Trash80toHP_Mini]

I guess that about does it, I've got a 32GB Mini PCIe SSD, a 2.5" case for the 'Book collection and a 3.5" adapter for using that box in the desktops.

I chewed up my QS drive by putting it into my G3 without realizing its limitations, so now I'm asking for advice on a partitioning for running 7.5.5, 8.6, 9.0, 9.1 and 9.2.2 that won't be destroyed by putting it into the wrong Mac:

630

6360

6500

BG3

DA

QS

MDD/FW400

150

190

5300 series

1400c

3400

WS/PDQ

Pismo

Blueberry TSiBook

Suggestions?
