That's exactly what I mean. Requiring a driver renders the "otherwise"

You have to have a kernel driver for ide, scsi, sata, sas, so why would RAID
be any different?
I don't have a kernel driver for seagate, maxtor, or western digital.
Why not?
Um yes you do, it's the IDE or SCSI or SATA driver for your root device
which is typically compiled into the kernel so it can boot off that device.
Every now and then, a new drive comes out that needs some tweaking of
the driver so the disk can be used by Linux, but mostly, the
IDE/SCSI/SATA sxtandard of communication is adhered to by the devices,
and you don't need a new driver to plug in that new drive.
I don't know if there's a "standard" for RAID communications.
It would be nice if the RAID cards spoke IDE/SCSI/SATA so they actually
did look like disk block devices and didn't need any specific kernel
driver. I'm sure there are reasons why this doesn't happen, I don't know
what they are though.
