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*.
