On the Drobo front my son wrote this to me:

I really liked Andy Ihnatko's explanation/review:

http://ihnatko.com/index.php/2008/02/18/sun-times-drobo-and-droboshare/

1) The Drobo acts as its own backup against drive failures. See above.
If you have all four slots filled, you can lose two mechanisms without
losing any data, according to the company. Lose one, and (just as I
said) you won't even know it until you glance over and see that one of
its status lights has gone red. Lose two, and Drobo will calmly excuse
itself from the room so it can have a good, long cry?but when it comes
back online, it comes back with all of your data.

Obvious weakness: with four mechanisms in the same physical location
and hooked up to the same bus and power supply, an external problem
(like a drop or a power surge) that takes out one drive can take out
all of them at once. To say nothing about a fire or a burglary at the
house. So there's still the usual, common-sense need for backups and
offsite storage, but that's still a huge win.

I'm learning a lot from this discussion
