I think you'll find that the ccd device in both -stable and -current is pretty good. I'm using it here to interleave two 330mb scsi's into a news/web cache for my small home system.... the individual drives can only do about 1mb/s reads/writes.... the ccd "device" does about 1.8mb/s reads/writes (yes.. the drives are old and slow) Peter -- Peter Childs --- http://www.imforei.apana.org.au/~pjchilds The internet is full, please try again in half an hour...
