Re: Disk replacement for DUMMIES

Carl,
add another two 6607 drives to it and after you' re  done with your
RAID config remove the two 6606's ... best performance is achieved
when the 4 drives not only have the same capicity (this is a must) but
when they are exactly the same type.
What is the feature no. of the controller you are replacing and which
one will you put in ?

Regards, Philipp Rusch
