raid controller recommendation

ICP Vortex cards.  They are expensive for sure.  But if you only knew 
the part of the force ;-)

Seriously though... those cards rock.  I did some testing years ago with 
RAID 5 and Ultra-160 drives (about a terabyte configuration).  We had a 
couple partitions and were able to get around 44 megs per sec writes.  
It was unreal.

Intel has bought them since I used the cards.  I understand they are 
still available and comes with linux drivers :D
