I am soon building a small server computer and for this computer, I am getting 2 7200rpm drives. I am going to setup raid 1 for these 2 drives so if one fails, I have the other. I have never used any raid arrays before so I was wondering if it was worth getting a raid card supporting raid 1, or should I just stick with software raid. What are the downsides of using both? Thanks to anyone who helps.
