If you are doing long sequential reads, you may see the difference. It's not as important as one might think. Several things do work nicer if the drive is a master, so it's a good idea all round __ Do you Yahoo!?

The motherboards with onboard raid are even better. You can have 4 HDs on individual controllers. All of my systems have /, /usr/src, and /usr/obj on different HDs for performance. The new round ATA-133 cables even get rid of the air flow problem. They are typically 24 inches long instead of the 18 inches max on the ribbon cable.

Yes I would recommend this, but I would also recommend not having a CD drive on the same bus as a heavily used disk (unless the CD is rarely used). I would also recommend putting /usr/src and /usr/obj on different disks to speed up makeworld (if that is important to you). - Mike To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message

If you're anal about cable neatness, air flow and all that weird stuff a single cable does have some benefit for some people. I prefer the two channel method whether it's two hard drives or a disk and cd-rom, since an IDE disk can only do one thing at a time.

2 drives + 2 IDE channels = better?
Hi, Is is better to run a 2nd drive on another IDE channel or on the same bus? Eg. IDE channel 1 = ad0 (main OS), IDE channel 2 = ad1 (other data - maybe MySQL and websites?) Thoughts, opinions? TIA Steve. PS. Is it obvious I'm building a new machine :) To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message
