Answer:
use RAID 5
Explanation:
The best option in this scenario would be to use RAID 5, this would all but eliminate the risk of losing the data. As you would need at atleast 3 seperate drives which would all act as backups for each other. Therefore, in the unlikely case that one of the drives were to fail or data were to become corrupt/lost the other drives would have a backup of that data which ca be used.
