Prior to the cloud, I ran at a coloc facility for 15 years. I break stuff much more often than having it actually fail. So... make yourself robust against human error first and you'll probably cover the hardware side as a side-effect. I am more likely to hose a machine during an OS upgrade and not have time to recover than I am to have an SSD fail. But spare capacity is a good idea, especially if you have real-time traffic.
