Sorry if this sounds a bit rude, but did u actually bother to read the help files that come with Clone CD. Cos if you did, you would know that u can Right Click on the Profiles and EDIT them, where you can then select read speed etc........
Also if you are using the latest version of Clony then it should have an option to create a profile called Clony in Clone CD which it can then update with the required setting at your command.
For the latest version of CLONY go to:

Lastly, The latest version of Clone CD is very powerfull. I have managed to copy games for backup successfully FIRST TIME and that is something to sing and dance about!
