my mac's old hard drive, with os x and all my data, has been through 3
macbook(pro)s without a single os x reinstall.  recently i dd'd it
into an ssd which replaced it with no issue.

i don't recommend this or anything; but i have on a couple of
occasions yanked the drive out of the mac and into a machine with more
storage and dd'd it as a backup (or is it archive?)  i only restored
from these images once, but it worked.

unless the interface is physically incompatible with your machine, i
don't see the problem.
