Just bought and installed a 20Gb hard disk as master and used the old 4.32Gb hard disk as the slave (both on IDE 0). The 20Gb is a 7200 and the 4.32Gb a 5300 (I think). Okay, the question is...

Is my new 20Gb disk being held back at all by being on the same IDE channel as a 'slower' 4.32Gb drive? Should I remove the 4.32 and just use the larger one?

Jet, the only thing that could slow down your new drive would be access times, thats why we never slave a CD rom off the master HD, the access time for a CD is around 100/120ms where as harddives are now around 7/9ms I think you'll not have any problem the way you have it set up, as most HD's these days are so close in access times that you'll not notice any difference at all, thats even if there is one. whats 1 or 2 milliseconds between friends.. lol

Nat, access time has nothing to do with it. It's transfer rate. Is one Ultra DMA and the other not? If so, the Ultra will back down to match the other drive.

The above does apply to CD-ROMs. Since CD-ROMs have such a slow transfer rate they don't ever have the Ultra DMA hardware. Thus they'll slow down any Ultra drive on the same chain.

Access time and transfer rate do often go together. A drive that has a slow access time probably doesn't have the state of the art interface hardware.
