maybe you should review this and restate the question?

Depends. Is your data important to you? Would you regret it if the data was lost suddenly? If so, then RAID 1 is the only 2-drive RAID level worth considering. Is your data more or less expendable, but you'd like some extra speed for video editing tasks? RAID 0 would be best. Do you find that neither scenario fits you? Then just keep the drives separate because RAID isn't for everyone.
