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. Bill Anderson John Andersen wrote:

On a side note, it's even better if we use LVM, so that when in the future we run out of space, we can "expand" it into another disk seamlessly. HTH,
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.
