I though I'd seen it all, with micro SD cards soldered to USB board and crap like that, but this is a new one on me....

Wow Let us see the bottom of chip and results.
Thanks for the pic.

Dang I wish I could stumble apon these! I have been buying from dodgy looking ebay sites for ages trying to get some interesting devices and all I can seem to get is ones with Alcor controllers pretending to be others and some really dodgy IDE branded ones that I cant find out anything about them.
But if the device works, and is advertised capacity and is also a decent speed.. does it really matter if it is an SD in there.. I doubt consumers would care or even know it was not usual.
does it work? maybe after recovery you could try h2testw on it?
BTW could you post a pic of other side and/or say controller number?
thanks for posting

I have such case about two years ago. Really crazy solution

I wonder if the SD cards were tested and failed at a controller level, but NAND was ok, and they decided to cut wastage/save on NAND chips and solder the SD directly to the PCB using same pinouts we normally would wire to adapter?
Using it this way, the speed should be same as any other USB device, shouldn't it?
BTW how did recovery go?

So far, OK.
I got the monolith connected up and read (Sergey @ Soft Center had to make new config for NAND reader, odd page size), found layout and ECC.
Correcting ECC (lots of, and presumably why the stick failed) now....

Yes, that's right. Luckily
