Right, and then there is the "discard" factor when using SSDs.
The SSD works better when knowing which data blocks are used and
which are unused; writing with dd will set everything as "used"
(this will not happen with mkfs + cp).

If you want to use dd to copy filesystems, it would be wise to
also use e2fsck with the "discard" option to rebuild the used/unused map
of the SSD after the copy.
Same thing with swap (I would hope mkswap implements discard), if you
copy the entire disk.

Best regards.
