I've heard of that happening with cheap consumer RAID. The idea is that you
can't find identical replacement hardware, and therefore your data becomes
unreadable because the hardware stores data on the disks in some sort of
unknown way. That's why I would stick with software RAID on my desktop
system... no reliance on some random Chinese vendor's RAID algorithm du jour;
you can just use the open source code that comes with your OS. Very easy to
setup and recover, and the speed hit probably doesn't matter much. Your
workstation shouldn't need to hit the disk much, after all.
I'm sure hardware RAID is better when you have a big vendor providing you with
some non-shit hardware though. I don't really know though, since I'm in
the "pay someone with a clue" camp when it comes to important servers.
