sum two disks using RAID or LVM?

[Γιώργος Πάλλας <gpall@ccf.auth.gr>]

Hi all!

A short question: I have two 500GB HDDs and I want to use their space as
one. Should I aggregate them with software RAID, or using LVM in regard
to data safety? If one of them malfunctions, is one of the two
approaches better?
