At LinkedIn, we are using a RAID-10 of 14 disks. This is using software RAID. I recently did some performance testing with RAID 0, 5, and 6. I found that 5 and 6 underperformed significantly, possibly due to the parity calculations. RAID 0 had a sizable performance gain over 10, and I would expect single disks to perform similarly. I didn't test it because it lacks some balancing ability that We would need.
