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

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?) For performance reasons a seperate channel is better. 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.

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

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. I also try to follow the 1 controller - 1 device rule. 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.

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!?
