IMHO, in almost all cases - at the end of the chain - is misinformation.
While this might be a bit bold - a lot of users don't even spend a few
minutes doing elementary homework like man md/mdadm/mdadm.conf and less
/usr/src/linux/Documentation/md.txt. Be it normal usage, or when
problems happen. Rumors and forum wisdom can be really damaging - not to
look far away - how many people keep believing that xfs eats your data
and fills it with 0s ?
It's hard to find cases, when md driver or mdadm was really at fault for
something. For the most part the typical route is: [bottom barrel cheap
desktop ]hardware/[terribly designed sata ]cable issues -> a user
applying random googled suggestions (with shaking hands) -> really,
really bad problems. But that's not md's failure.
I'd put lots of responsibility on [big] distros as well, which have been
trying (for many years already) to turn linux into layers of gui/script
wrapped (and often buggy) experience, trying to hide any and all
technical details at all cost. But that's OT ...
Be it flexibility, recoverability (with cooled head and after panicking
while being /away/ from the drives and md) or performance (especially
after some small adjustments - namely stripe_cache_size for write
speeds) it's hard to challenge md. And some awesome features are coming
too (e.g. http://thread.gmane.org/gmane.linux.raid/34708 ).
