Will using a slower IDE drive slow down faster drives on the same interface?

If I install an older hard drive with a slower bus speed on a newer, faster controller, will this degrade the controller's performance? Or will faster drives still work at the higher speed?

    Accepted Solution

    If you are connecting both the disks to the same ide channel, then you'll get the speed of the slower disk. Also if you want to access both disks at the same time that won't work, as an IDE channel can only address one device at the same time, so in this case it is better toput every device on another channel. If you add an additional IDE controller you'll get the speed of the slowest device on the same ide channel of that controller. You can of course get speed reductions even if all devices are on different channels if your OS or software has to wait for a slow device to finish before it can go on...

    Thanks, that's pretty much what I was afraid of.
