As I understand it SATA controllers are always always one device per channel, even if it's the same controller. Meanwhile SCSI is designed so you can have a bunch of things talking on the same cable at once without it being a big deal. You'll probably get better performance than with SATA. -- Matthew Miller mattdm@xxxxxxxxxx <http://www.mattdm.org/> Boston University Linux ------> <http://linux.bu.edu/> Current office temperature: 78 degrees Fahrenheit.
