I hope changing ataraid doesn't mean removing the ability to access the=20
underlying devices that comprise a RAID array.

Having this ability is quite useful as it allows you to monitor the status =
of=20
the subdisks easily (with smartmontools) as well as do things like read the=
=20
serial numbers (atacontrol cap adX), etc..

I don't know if you can use smartctl, atacontrol, etc with graid3 as I don'=
t=20
use it.
