RAID (Redundant Array of Inexpensive Drives) comes in many flavors but the consumer in general uses raid 1, mirroring.
One disk is an exact copy of the other so if one fails you still have all of your data on the other drive.
This is an excellent way to protect you against loosing your music collection due to hard disk failure.
It won't protects you against dropping the unit (kids, cats, dogs, drunk), water, fire, theft, etc.
It won't protect you against user errors like deleting the wrong files or applying the wrong tags. Sounds logical but I have the feeling that a lot of people think they are save because they have a RAID system.
As far as user errors are concerned, the difference between RAID and a single HD is that with RAID all your stupidities are stored redundant.
Mean Time Between Failure for a HD is 500,000 hours.
What is yours?
Make a backup before you say to yourself "I should have made a backup"!
