> bs=102400 or bs=128k will dd faster though.... you can play with that. That's not my experience. 8k dd runs at disk speed (30-40 MB/s) on all the machines I've used recently when copying between different disks on different ATA controllers. Between disks on the same controller I only get about 13MB/s (why?) but there's no difference between 8k and 128k dd. -- Richard To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
