It's funny you should mention this as well.  I just recovered from my
computer woes.  See, I had a RAID1 hardware mirror with 3Ware and I detected
what seemed to be a harddisk failure.  No problem, I should have high
availability and tolerant this fault nicely.

So, how come I had to end up ripping the 3ware out and reinstalling on a
normal IDE disk?  (a few times too!)

Because sometimes the best designs are not going to work without a lot of
field testing.  Either that or the goals are too ambitious (kind of like
those surge protectors that supposedly can stop direct hits of lighting).

For the record, the RAID somewhat worked, but it didn't provide the fault
tolerance which I was looking for.  I ended up losing so many man hours, I
was MUCH better off relying on my network server's RAID and backing up data
there.  No data was lost thankfully but I did not benefit from high
availability because the RAID system failed for me.  Next time I am going to
go SCSI RAID, but for now, no more RAID.

It's not that the designers are liars or crooks, just it's a bit hard to
test for hurricane resistance when you can't just say "hey let's go test
this against a category 5 hurricane!".  If I could run into this issue when
I had the ability to do field testing, imagine running into scenarios where
you are up against a force of nature that does not appear that often.

That said, like my RAID scenario, I paid a lot of extra money and spent
extra time accomodating and ensuring the RAID1 was setup to work.  When push
came to shove, my RAID1 solution did not provide all the features I wanted
anyway, so I wasted all those resources for nothing.  It's hard to
pre-design for certain things, and you might end up spending more money
without getting what you really want.  In that sense, you were better off
spending it elsewhere, ala opportunity costs.
