tar and dd do it differently. dd is works at the block/device level and does not know anything about the file system. It will copy the boot sector and so on. tar on the other hand reads files.
So do you want to clone the device or copy al the files? Note that to close a device you need identical hardware. tar beach it works with files can copy them even to a different kind of OS, say from Linus to a mac. Very different.
