Harddisks have a bad reputation too. They fail regulary.
Not that frequently.
Anyway, I would not feel comfortable about backing up data residing on a harddisk to another harddisk. I believe that a backup media has to provide different characteristics than the original media. An incident that harms original should not harm the backup.
Why?
What about if a firmware bug destroys all data on day XXX on all harddisks ? Well, extra paranoid maybe and of course I have not thought of all possible things that *could* happen.
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.
