Are you saying that you only buy one model from one maker? In the
mid-nineties, every ISP in Chicago dumped *all* of their SCSI Seagate
Barracudas for failures. The next year, at work, I had an external box for
a Sun server that had *four* of them: in the next year, Sun replaced
various of them *five* times. Meanwhile, the IBM drives inside the server
were just fine.
