RAID10 on tha Intel ICH will make u happy, as u have a boost in speed, as well as a backup set too..
And what will happen when, for whatever reason, some important files gets deleted and the RAID has started to sync?

Oh, its not a offsite backup, its a quicker scratch with a second copy, of course.. U never use raid as a backup, having your data in one place wont stop, fire, flood, theft, etc, or viruses, file system corruption, accidental stupidity like delete or format, etc.. RAID just covers u for hardware failure, its not normal or often that 2 devices fail at tha exact same time, as well it can give u some extra performance to work with at tha same time, or in tha case of RAID0 just performance when failure isnt as important.. I guess I shouldnt of used tha word "backup" in that case, what I really meant was "second copy"
Tha idea in this case, as for scratch volume, u use it to work with your files, and if any one of tha 4 RAID10 hard drives die, u replace that drive, it will reclone from tha good drive.. U get to enjoy no downtime if needed, no reconsrut of files as per making a new volume from backup, losing what isnt backed up yet, and some extra speed..
