12:50 PM EDT 		How many people are going to follow this advice and lose ALL of their data when one of those drives fails? A 1TB or 2TB drive is inexpensive enough -- even considering the enterprise-class drives that are strongly suggested for use in RAID setups -- nowadays that, IMHO, it's criminal to suggest that users set up RAID 0 devices when they should be setting up RAID 1. (Hey look! You still get to use a "cool acronym".) Either way you still have to do something that's still considered decidedly UNcool -- backups -- though I would be a lot more nervous about missing a backup of a RAID 0 device than I would a RAID 1.

I agree. RAID0 has always seemed a bit pointless to me too. I suppose it had its use for combining drives before lvm made it trivial to combine and resize and recombine drive space resources. I would also recommend SAS drives rather than SATA for setting up RAID1. SAS is much more expensive, but tons more reliable in my experience.
