While not all about stress testing the drive,I may have a stress reducer for
many of us

In several POS arenas we use a hardware mirror controller called "Duplidisk"



The best article explanation of the device is here:

Do take note that Duplidisk is totally OS and application agnostic  for it's
IDE device role.

Of a 2005 project run involving some 2900 of these there were maybe 3
failures  on systems relying on the Dupli, and 1 of those was my being given
an incorrect firmware update- which was recoverable from. The other 2? one
was in a lab confirming my firmware bug, and the third was "pepsi
syndrome-sadly dupli is not pepsi proof.
But as a real world dragonslayer it just plain works!
