I can explain why people aren't using RAID... IME It's because they think they are. But they do it wrong, and only find out when things go wrong.

Most if the disasters I deal with involve "hardware" RAID cards. I won't single out PERC or MegaRAID because that wouldn't be fair.

People are using stupid operating systems (i.e. not FreeBSD or Solaris) and the HBA acts as a volume manager. The OS is clueless when a drive goes flaky as all it sees is one big drive, and the first the know if a problem is when the final one croaks. (Who is there to see the identity lamp flashing red).

Companies pay lots of money for this kit (to run Windows) and believe what they were told when they bought it. The more kit costs, the more lusers trust it.
