i currently have a 13gig 5400 hd on ide 1 (os and apps)with a cd/rw and a 60 gig 7200 on the second ide (audio)

my question is.....does having cd roms on the same bus as a hard drive slow your overall performance because i read somewhere that cd roms run at ata33 and that if a cdrom and hd are on the same bus the harddrive will then run at ata33 is this true? and also if i get a second 7200 hd for audio on the second bus will that slow me down rather than just sticking with the one drive..if they're both ata100's?
 
to my knowledge every ide channel operates at the slowest of the two devices attached.

The lesson they learned me was: two HDDs on controller 1, your writer & cd-dvd-3rd HDD on the other. Wouldn't use the 3rd HDD for audio though, more for archiving things (but what would you have the cd-rw for then ;) )

Your information is incorrect.

Actually, this has been answered a bunch of times before, do a search if you like. However any of the newer IDE CD-ROM / DVD drives will not impact the performance of any drive they share an IDE bus with.

On the other hand, it is a very good idea to have devices that will be running at the same time on different IDE buses. IDE doesn't like to read and write at the same time - it will do it, but performance tanks. The best setup to take advance of this is:

Primary Master - Your bootable system hard drive
Primary Slave - A CDR burner.
Secondary Master - A big, fast data hard drive.
Secondary Slave - A DVD or CD Reader

With this setup you can burn data to CDR from your data drive or copy CDs with maximum efficency.
