RAID Decision

[smckay]

I have a load of old home movies, record collection and other data that I want to store on hdd's. In order to provide some security I want to RAID the drives;

1. As I will be using the drives as storage and read/write will be rare which is best RAID0+1 or RAID5?

2. I know about minimum number of disks but is there a maximum?

3. If the mobo offers RAID support is this better than a RAID card? Or is a card best?

4. Should I be looking at anything other than the above?

Thanks for reading

I will be backing up seperately to the RAID option, sounds like I want RAID5 but I will have to look into a RAID card, cost etc to see if its worth the cost
