Integraters tell me that right now Enterprise SATA drives are
significantly better than ordinary SATA drives, while not costing much
more. One also pointed out that in previous generations, the
underlying disk technology was the same, but at the moment SCSI drives
are on the previous generation of recording tecnology, hence the lower
densities for SCSI drives.

So studying the past might not work very well for drives you buy
today.
