I added some more iozone runs, as well as those of rawio. These are much
fewer (as file-system parameters don't affect rawio) and easier to
interpret:

    * It makes no difference to the SSD, whether your access is random
      or sequential
    * SSD clearly beats the HD in rawrite, although, at "only" 88Mb/sec,
      the results are far from the marketing...
    * SSD connected to plain SATA port strongly beats the same SSD
      connected to the fancy SAS controller (mpt)
