External DVR-S111B & DVR-111D, difference?



Dearl all, I am looking for an external Pioneer burner. Although there seems to be nothing available on the official website, I found two models on ebay. One is the known DVR-S111B, while a seller offers the “external DVR-111D” (see below)


Okay so my question is, are there any differences between these two? The second one seems to use the “SYBA SD-U2PLA-525 External Enclosure” (from the picture provided). I don’t know if they are non-custom enclosure as I could not get any information from the official website!

Also, if anyone could suggest me which one is better to go with, I would highly appreciate it. Thank you.
