On my setup, i am using an MSI Motherboard together with a Maxtor SATA-150 HDD. My BenQ 1620 is conected as the master (without a slave), on the primary IDE channel.
Although I am not an expert on the subject, I want to confirm that I am using this setup for almost 5 weeks now and I NEVER had any problems (slowdowns, failures, costers etc. ) with the BenQ1620 .
Good luck with your installation,
