This really sums it up succinctly.
If you watched the cases of disaster that swing past linux-raid, the
ones who always walk away whistling a happy tune are the ones who stop,
think and ask for help.
The basket cases are more often than not created by people trying stuff
out because they saw it mentioned somewhere else.
I'd suggest that users of real hardware raid suffer less "problems"
because as they pay a bucketload of money for their raid card, they are
far less likely to cheap out on cables, enclosures, drives and power
supplies.
Most of the tales of woe here are related to the failures associated
with commodity hardware. The 8TB I lost was entirely due to using a $15
SATA controller.
