[I hope this isn't off topic]
A different drive inside with a smaller buffer. Probably manufactured in August 2014 (warranty expires 27/08/2016). Enclosure feels pretty robust by modern standards.
Everything is consistent with it being a Samsung, judging by the buffer size probably a SN-208FB.
(I haven't opened up the enclosure to verify the model as it is supposed to somebody's Christmas present.)
Drive not detected by Transcend's firmware update utility (hasn't been updated since 2012, although listed as a downoad for this model).
