Coincidentally I was talking with a sysprog over coffee about raid 10 and he said that the survivability of raid 10 was not as good as 5, there are relativly likely disk loss patterns that can cause you to loose all the data, when a raid 5 setup with the same (or less) redundancy could survive. He mentioned it cos it actually happened over the weekend :( I dont know how the performance compares. I've always used 0 for raw throughput and terrible survivability, or 5 for robustness and a bit extra speed. - Steve
