thank You for Your answer. Things are quite clear now ;)
As I am curious, there are two more questions:
Is there really no hardware support for reading, writing
and repairing the RAID in pseudo hardware controllers?
What are the missing functions of ATARAID compaired to
MD raid? (The latter is just software raid, right?)
With this background information, is there any reason to use
ataraid instead of md raid?
does quasi-hardware mean that this kind of raid
controllers are just simle IDE controllers and the
real RAID functionality is done by the drivers?
