Hello
If I want to move FreeBSD to a new hard drive with:
What is the optimum size for "bs" ?
If I do not use bs, and leave it default then bs will be 512 bytes and it takes forever. I've used bs=20M but I want to know what is the optimum size for bs when dd-ing from a sata drive to another and also the optimum size when dd-ing from a usb stick to another.
(I'm not interested in other ways to move data to a new hard drive, I'm only interested in cloning.)
thanks and best regards,
