I have a couple of really old clunky 330mb SCSI drives, that can only push about 1mb sec reads, 0.8mb sec writes... put together and striped the ccd device does a good 1.6mb/s reads/1.4mb/s writes...
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.
