RAID0 is great for increasing throughput, but it is the most risky RAID configuration possible. I would never run /home on RAID0 unless I was doing something like two drives in RAID0 but doing nightly backups to a third drive in case my RAID0 volume broke. You're flirting with disaster running /home on RAID0.
As we often say, RAID isn't backup. Or in other words, RAID6 is (essentially) no safer than RAID0 if you don't have backups. I would never run /home on any storage configuration without regular backups, either. From that perspective, it seems odd to warn someone about RAID0. Non-redundant arrays increase the risk of down time, but recovery from data loss is an orthogonal concern.
