  disks are mirroring with more than 2 disks. Writes to all disks, reads from
  one with shortest seek time. Acknowledges but ignores problem posed by
  lo:disks. Also considers that newer disk technology does not have linear seek
  time $(a+bx)$ but rather $(a+b\sqrt{x})$. Shows that with either seek
  distribution the average seek time for workloads with at least 60\% reads
  decreases in the number of disks. See also bitton:schedule.}
