For the time being, these SATA disks will operate in IDE compatibility mode, so

performance.
I assume you mean to dedicate one drive to boot/swap/upgrade, and the other
three drives to ZFS. But I can't mirror with only 3 drives, so I think RAIDZ is
best, wouldn't you agree?
What I would do:
2 disks: slice 0 & 3 root (BE and ABE), slice 1 swap/dump, slice 6 ZFS
mirror
2 disks: whole disk mirrors
The ZFS config would be a dynamic stripe of mirrors. Later, when you spring for
1TByte disks, you can replace them one at a time, and grow with minimal effort.
KISS
Your challenge will be how to back this beast up.
