Yes, my point however is for low budget stuff with software raid the driver support is not yet there 
in a vanilla kernel.
I can't just whack a sata drive off one of my promise SATA150-TX4 controllers, pop another one in 
and have the kernel rescan the partition table and realise a new drive was present. (YET!)

My entire point was that for the types of controllers that were being discussed (Highpoint was 
particularly mentioned, but you can really interchange any multi-port ATA/SATA controller for this) 
that the kernel support was not there *yet* but hardware raid or faux hardware raid will buy you 
this support *now*.
