  abstract = {RAID5 disk arrays provide high performance and high reliability
  for reasonable cost. However RAIDS suffers a performance penalty during block
  updates. We examine the feasibility of using "dynamic parity striping" to
  improve the performance of block updates. Instead of updating each block
  independently, this method buffers a number of updates, generates a new
  stripe composed of the newly updated blocks, then writes the full stripe back
  to disk. Two implementations are considered in this paper. One is a
  log-structured file system (LFS) based method and the other is Virtual
  Striping. Both methods achieve much higher performance than conventional
  approaches. The performance characteristics of the LFS based method and the
  Virtual Striping method are clarified.}
