If reliability is the major issue, then use the mirroring or stripping
options of LVM. Of course, it always helps if the disks are on different
controllers.

On a side note, it's even better if we use LVM, so that when in the future

LVM has some serious risk involved.
Let us assume that in any give day you have a 1 in 3,000 chance of a drive
failure.
Now assume LVM is in use, and the LVM is made up of 3 drives. You
now have 3 in 3000 chance of failure, and any single failure may take
out your entire file system, since you can never predict where a file
or portions of a file will reside.
