How did you get two drives into RAID5 and if so, why?

Just two days ago I built an Arch NAS/HTPC with two 2TB WD Caviar
Green WD20EARS (the ones with 4k-sectors). I used the latest iso from
build.archlinux.org, the one that Thomas suggested, and everything
went happily fine. I used parted's interactive mode to partition,
followed by mdadm and mkfs.
Parted automatically warned me about an unoptimal sector alignment
when I tried to put the first partition at 0 (the first partition
should start at 2MB), but if you want to be extra-sure just check the
the '-a optimal' parameter. About the disk reliability I can't tell
much, but I already transferred some 100GB to it, and of course I had
the first RAID5 build, which took a few hours and ran through the
whole disk. Also, smartctl doesn't have anything bad to say.
