I'm not sure I agree. Years ago I used some really nice Compaq 
Smartarray things which were simply excellent, but ever since then I 
have been disappointed by hardware raid.  Slow and clunky...
I bought a couple of 3ware cards recently and haven't been impressed 
with their raid 5 performance at all.  20Mb/s max read/write rates...
Software raid under linux is pretty good and will probably outperform 
anything but a really top end hardware controller (think decent SCSI cards)
