Really depends on what your application.  For the most part software raid will beat cheap hardware raid in preformance and relyability/recoverability, if we are talking modern hardware.  If your looking for a dedicated nas box I would suggest looking into sun's zfs.  I've been researching it for a couple months now for a project and its quite a nice package, easy but powerful.  Problem is it doesn't have native support in linux, due to licenssing incompatability.  It is available through fuse.  However if your looking for a dedicated box opensolaris, or bsd offer better preformace and more features, due to native support in the kernel.

If your just looking for preformance on an existing system then investing in a good 3ware card, or something similar may be the way to go. But you can put together a basic, consumer grade, nas box with opennas (bsd) or eonas (solaris), for about the same as a comercial grade raid card.

Guys,

I'm thinking of setting up a raid array and usually I just use the 
software raid tools linux provides. But I'm wondering what the 
advantages would be to use the hardware raid controller. Any preference 
out there between using the software or hardware raid?

Cheers. Steve.
