Does everyone have to post "does ccd work?" or "how fast is it?" every time they're interested in using ccd? FAQ: Yes, ccd works. Many people (myself included) use it daily for our main filesystem. If it didn't work, there would be a lot of very unhappy people. Yes, ccd will give you a moderate performance increase. No, it will not double your performance with two drives. ----------------------------------------------------------------------------- Michael L.
