I was using the Asus Z87 Pro and the Intel DZ68DP. I did a couple of tests with the connection types you were using and others I had available. With pv or a very optimized bs parameter, you can do a 4 TB drive in less than 7 Hours (6 Hours 50 Minutes at a current speed of 150 MB/s). In regards to HFS+ I would not know, am just trying to help on the "speed" part. The nice thing about pv apart from the speed is that it shows the progress, current speed, time since it began and ETA. This has to be done of course from root: pv /dev/sdb There is also pv (Needs to be installed first) that checks for the fastest speed on both drives and then proceeds on cloning. Adjusting the bs parameter can increase the speed, for example, I have 2 HDD that I know have a read/write speed greater than 100 MB/s so I do this: dd if=/dev/sda of=/dev/sdb bs=100M In my experience, I don't think there is something faster in the command line as dd. When I made my first clone, I did all of the partitions except HFS+ and it went very quickly. I have tried Clonezilla (and it was MUCH faster), but it does not support HFS+ smart copying, which I need. I need to clone the following partitions (including UUIDs) Is there a way to run this drive copy that takes less that 96 hours? I am open to using tools other than dd. SATA (If I find/buy a cable, gotta love laptop CD drives).USB3.0 (If I find my other drive caddy).Gigabit Over-The-Network clone (Really do not want to even try this).I might be able to use the following protocols: dev/sda is a local drive and /dev/sdb is a remote caddy. I am doing a dd on two identical drives with this command: dd if=/dev/sda of=/dev/sdb bs=4096īoth hard drives are the exact same model number, and both have 1TB of storage space.
