better disk reliability on a desktop machine

[lars]

-	/usr/ports/sysutils/smartmontools
	can help you monitor your HDDs

-	RAID 0 doubles the chances of HDD failure and thereby data loss

-	DVDs and CDs are chronically unreliable, see the 14/2005 issue of the
	German c't magazine where they tested CD/DVD burners and media
	and found out that a lot of media are neither burnable nor readable
	by a lot of CD/DVD drives

-	But since you need high performance on your HDDs and backup to tape,
	you're probably fine

-	A hybrid approach of backing up data to a separate box
	and to some removable media is probably the best.
	And, nowadays at least, not even that expensive,
	e.g. Mini-ITX boards are cheap and fast enough for this purpose.
