Default Older HD causing underperformance?

I heard somewhere that when you have 2 or more HD's, the one with the lowest rpm's will set the pattern. For example, if you have 2 hard drives that run at 7,200rpms and another that runs at 5,000, they will all run at 5,000 even though the other two can go higher. Is that true?

Is it possible that my 6.5gb causing underperformance of my 200gb? I dont know how many rpms the 6.5gb runs at, but i do know that the 200gb is 7,200 rpms. Should i ditch the 6.5gb and just keep my backups on the new drive? I DO NOT want to partition the 200gb, so dont suggest it.

I have a computer with stuff in it.

All the hard drives will run at the speed they are supposed to. A 5500 RPM drive won't slow down a 7200RPM.

However if a ATA 133 HDD is on the same IDE channel as a ATA 66 drive it will only run at 66mbps. Also, if 2 ATA 133 drives are on the same channel, it will run at ATA 133, but it can cause problems.
