If you're really set on ext3, specifying larger files and fewer inodes
will definitely shorten the partition build and fsck times. I have some
Seagate 1.5Tb drives, and I decided on two ~700Gb partitions instead of
a single giant one. You might have to fool around with fdisk to get the
sizes just the way you like.
Details are below.

This script ran in about 25 minutes on a CentOS system:
#!/bin/ksh -x
# make filesystems with fewer inodes, larger files.
export PATH=/sbin:/bin:/usr/bin
date; mkfs.ext3 /dev/sdb1
date; mkfs.ext3 -J size=400 -i 65536 /dev/sdb2
date; mkswap -L SWAP-sdb3 /dev/sdb3
date; mkfs.ext3 -J size=400 -i 65536 /dev/sdb5
date; mkfs.ext3 -J size=400 -i 65536 -m 2 /dev/sdb6
date; mkfs.ext3 -J size=400 -i 65536 -m 2 /dev/sdb7
exit 0
Using fewer inodes added a total of nearly 80 Gb of available space on
/space1 and /space2, compared to one huge partition with default inode setup.
