I have to make a note of this. I still have dual opteron boards
running at work. One such system has 2 promise sx8 controllers and 18
to 20 WD 250GB SATA 1 disks.

Links please. I really could use 8 port or greater SATA2 controllers
in my file servers that do not include hardware raid that I will never
