Ultra II 480G Questions....

As much as I’d like to accept SanDisk’s suggestion that drives with different firmware are OK to use in a Raid,

Adaptec specifically states NOT TO DO THIS!

Would SanDisk Like to re-visit their answer, and provide me with an exchange of one of the drives for a duplicate of the othere?
