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):
zpool list
NAME SIZE ALLOC FREE EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT
zroot 428G 216G 212G - 47% 50% 1.00x ONLINE -
pou 232G 49.9G 182G - 39% 21% 1.00x ONLINE -
/pou is on an Samsung SSD 840 EVO 250GB:
smartctl says:

12 Power_Cycle_Count 0x0032 099 099 Always - 8
177 Wear_Leveling_Count 0x0013 083 083 Always - 199
The Wear_Leveling_Count shows that it's probably beyond the spec already 8-}

Have you checked poudriere configurations MAKE_JOBS parameter?
Here is a snippet from poudriere wiki:
By default MAKE_JOBS is disabled to allow only one process per cpu. To
allow it anyway, ALLOW_MAKE_JOBS=yes in your /usr/local/etc/poudriere.conf:
echo "ALLOW_MAKE_JOBS=yes" >> /usr/local/etc/poudriere.conf
