  comment = {See wolman:iobench. Used IOBENCH to compare normal disk
  configuration with striped disks, RAID level 1, and RAID level 5, under a
  random I/O workload. Multiple disks with files on different disks gave good
  performance (high throughput and low response time) when multiple users.
  Striping ensures balanced load, similar performance. RAID level 1 or level 5
  ensures reliability at performance cost over striping, but still good.
  Especially sensitive to write/read ratio --- performance lost for large
  number of writes.}
