the advantage of DBAN is I can boot directly from the CD and at the prompt type autonuke, to do a DOD wipe of ALL drives in the machine. I can take out the CD after that has started, put it in the next PC and repeat the process, while the first one is still wiping. DBAN is lean so it boots faster than most live distros, and it automatically does multiple overwrites with the command I used as an example. There are other command options available. DBAN gives multiple options of HOW you want to overwrite the Drive as well

Sure dd works fine, there is nothing wrong with that method, dban has just been sorta streamlined for the purpose of wiping drives imho. I'm sure both methods take about the same amount of time to complete, depending on the number of overwrites you do to the drive.


Code:

And do some tests with different block sizes to see what is fastest---eg
bs=1G count=1
bs=512M count=2
bs=256M count=4
etc.

Each of these copy the same total amount of data, but the speed will change with the block size.
