With the Highpoint driver I get a drive failure and the card starts beeping. I fire up the management util, remove the faulty drive, swap it out and insert the new drive in the array. The array starts rebuilding - no effect on the uptime and only a slight loss in throughput. Plus it's seamless.
Yeah, md+mdadm can do all this right now, provided the hardware and driver support is there...
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*.
