UDMA66

[drizzle]

Alright, I have a quick question. If someone has a UDMA 66 controller card (Say I/O Magic maybe) and they have two hard drives, one is a UDMA 66 drive and the other is just UDMA 33, does it matter where on the cable the UDMA 66 drive is plugged into--of the two connecters for the drives that is?

Hmmmmmmm, My answer in DMA Conflict could be relevant here, I think you will have a slowdown....

How about the cable thing? If the UDMA 66 drive is the only drive on the cable does it matter which one of the drive connecters you use? Like, is it only the connecter on the end that would support the UDMA 66 mode?

Sorry for asking such a crazy question but I was curious...

No, the whole cable is UDMA66. I think I get what your saying...You can hook your '66 drive up to any port on tha cable, and just hook the old '33 up to a standard IDE cable, and the IDE port on your motherboard, or on a controller card, or wherever it may be. I think if you would have left out that whole second drive part it would have went over a wee bit better http://www.sysopt.com/forum/smile.gif but that's ok, no worries

I have heard that if you place the ata 33 card in the first spot on the cable and the ata 66 in the second then they will both operate as ata 33. So.. the ata 66 must go in the first spot. I'm not positive on this but pretty sure!

umm..huh? Why would you hook a 66 and a 33 card together?
