Mike, sorry I am taking this off list - if you want we can bring it back on for the education of all, but it seems to tangent from discussion..anyway I am planning on implementing a promise 6 channel raid 5 IDE card and you mentioned " Promise puts the drive hashes on the controller". I am not sure I understand this, or what the ramifications mean. At the least, i want to be able to understand what I may be getting myself into, if not try to minimize any painting myself into a corner... Any info would be appreciated..
