Those are likely date codes: 2011, week 22. And possibly 8-00B or
-00D are board revisions. They may not be identical, but all the
components are in the same place and I'd bet software will consider them
the same thing.

The Startech USB chip is the same, a D720200F1. A much better
picture of the Vantec version:

Newegg does not have the Vantec any more, but they did:

Anyway, the eight-pin IC is an Atmel 25F512B, a 512K-bit flash ROM for
firmware. It's possible there are firmware updates for these cards, but
unlikely the vendors have them for end users.

One engineer is honest, the other is optimistic. :)
