It does not have to be that way. Use only one disk for the system
and the second disk for a poudriere ZFS pool ?

Use the same setup, but with ZFS.
I think, but have not checked it, that poudriere uses zfs clones,
which is ***way*** more efficient than copying the whole tree for
each poudriere builder jail.

3.5" or 2.5" ?
Putting the poudriere storage on a SSD might be very helpful.
This is my builder box (8 threads, Intel(R) Xeon(R) CPU E3-1230 V2 @ 3.30GHz,
32 GB RAM):

The Wear_Leveling_Count shows that it's probably beyond the spec already 8-}
