This is just not true.  If you want the best performing drives out
there today, you'll be using SAS (Serial Attached SCSI) or Fibre
Channel.  There are still 3.5" LVD SCSI drives (the old parallel style)
that beat the pants off the fastest competing SATA drives because they
spin at 15K RPM and have longer MTBFs.  Yes, these drives cost more than
SATA, but there are many reasons to use them.
