This is either your homework or else your employer is the biggest cheapskate I have ever heard of.

I suspect the former.

Gracey, when we use raid facility ,we can connect only 4 hard  disk,because no any option r available in our motherboard thats why we connect more then 4 HDD. i think like this if any other answer u may get p, please inform me.

The most conservative RAID is where two disk are using together as a pair, both have the same data.
