Some years ago, 3ware made good-quality RAID controllers which had good
Linux drivers, and didn't cost too much money. Unfortunately they've been
bought out and while they're still available, the product line is stagnant.

What do people recommend for a hardware RAID controller for desktops and
small servers these days? Ideally something which:

* Handles drives of modern size and speed.
* Has a non-vile CLI management interface (MegaCLI I'm looking at you).
* Has a Nagios monitoring plugin which works reasonably well.
* Ideally in the case of a Linux desktop would pop up a little warning
  saying "one of your drives has died".
