Hi,
I'm trying to add a second drive to the new to me SuperMicro server I
just purchased off ebay. It has an Adaptec AIC-7899 U160 controller
(dmesg below) but I'm finding a lot more U320 drives for sale than I am
U160s.
Will a U320 drive fall back to the U160 bandwidth? I'm finding
conflicting advice on google, some say no problem, other say I'll kill
the U320 in short order, not seeing any hints in the man pages.
Thanks,
Jeff Ross
