This is possibly germane. I have very recently rebuilt my home
file server, because the disks were wearing out, I was starting to
be squeezed for space, and (P)ATA drives will soon start to become
scarce. The rest of the system is old, a MSI KT6 Delta FIS2R MS-6590
motherboard, Athlon 3200 XP processor, and a couple of old (one very
old) Promise ATA cards. I can't afford to replace the lot.
I've rebuilt it on 4 new 500 GB disks, with a single slice per disk,
multiple partitions, the root filesystem mirrored on all 4 drives, other
filesystems and swap each on a stripe of two mirrors, and everything
labeled. I chose to have a single large /home partition to avoid the
spare space over there not here syndrome, which will be "fun" when an
underlying mirror is re-silvered, and even more "fun" if the system
panics or my UPS fails when /home is active.
I decided not to use ("dangerously") dedicated disks.

To avoid finger trouble I threw together a makefile (which is as usual
somewhat indigestible) to set up the disks and GEOMs and perform the
restores. It may be of use to others.
The GEOM names are a bit strange because I'm including the abbreviated
machine name in each, and I seemed to run into problems with 9 character
names.
Performance is adequate. Copying (tar | tar) an 18 GB package
collection within /home took 21 minutes. I intend to run disk benchmarks
and try different gmirror balance algorithms and split sizes (easy) and
different gstripe stripe sizes (harder) to determine what suits me.
I'll be doing the same thing with the simpler 2 disk mirror workstation
in a week or so. I'll post that makefile too.
"make -n" output and initial disk label (where you set the partition
sizes), the makefile, the new /etc/fstab and dmesg follow.
Note that this approach only works if you can initially boot the system
from something else (LiveCD, FreeSBIE, ...) and have your dumps
accessible too (external USB hard disk).
If you can't, look at http://people.freebsd.org/~rse/mirror/ which is
Ralf S. Engelschall's ingenious howto remotely upgrade a single disk to
a mirrored dual disk system. His introduction states:
The following is a step-by-step command list for remotely
converting a production FreeBSD 6.2-STABLE (i386 or amd64 PC
architecture based) system from a single-disk/single-slice
(ad0s1) to a two-disk/single-slice (ad0s1 & ad1s1) GEOM mirror
(gm0) based setup without the need for console access or
Fixit/LiveFS CDROM:
