Answer:
Step-by-step explanation:
First, the thing that you should do is to install two hard disks, one on a different disk controller. This will prevent loss of data if one of the disks or disk controller suddenly fails. The next thing that you should do would be to create a RAID 1 volume for the system volume. This will mirror the disks, and drastically reduce redundancy between them as well as increase the disk access performance up to double what it was before. This would be the best course of action in order to accomplish the requirements that you need.
