I have an A-DATA 8GB MicroSDHC card from NewEgg.com. On the back appears:
9A0275
MMAGR08GUDCA-DB
S FLH3E6X3 941
If you search for MMAGR08GUDCA-DB, you’ll find posts listing this same product identification number for Transcend cards.
Corporate profiles list different CEOs (Peter Shu for Transcend, Simon Chen for A-DATA). The product details, however, seem to indicate that they’re the same company, or at least share suppliers.
This is relevant only because A-DATA cards sell for slightly less than Transcend cards ($17.49 vs. $20.99). Additionally, if you don’t need the SD adapter, you can get the bare A-DATA MicroSDHC 8GB card for a few cents less ($16.99).
