Brand probably matters a lot.  The 3ware and Areca's I'm inclined to 
trust.  They're true hardware RAID controllers and not just fakeraid. 
Things get a lot murkier when you get into the bottom half of the market.

But for smaller shops that can't afford to have 4+ of everything and 
don't need the CPU offload that a hardware RAID controller offers, Linux 
Software RAID is a solid choice.
