- The hard drives are much better performers than people think. We've ran about 600 minis for three years now and have had 10 hard drive failures. Thats a pretty good rate. I think it's that way because these minis are colocated in a data center where they are not bumped around (like a laptop), they have clean power, and the humidity and temperature are closely monitored.
- High traffic isn't a problem. I ran a site on my personal Mac mini that had about 2 million page views per month. Jailbreakme.com currently runs from a mini in our center and takes in about 5 million per month. It all depends on what you do with the traffic gets there.
