interesting. so this is probably a fake? but the same 8GB card has similar values but a different manfid and oemid..
I wouldn't say 'probably', but it's at least noteworthy that you have cards with two different manufacturer id fields from a company that claims to make everything themselves. If one of the two is fake, it's at least not clear which one is.
To follow up on this, the two tests you posted from the Lexar 8 GB cards (class 4 and 6) show almost identical results, which is highly unusual.
There are only two reasonable explanations for this:
* They are in fact identical controllers and flash chips, but one of them has been flashed to report a different manufacturer ID. This still doesn't guarantee that they are both authentic (e.g. one could be a graveyard shift run from scrap chips), but it's a good hint
* You accidentally measured the same card twice and one of the two test runs you posted does not match the card. Can you look again to be sure that the results are matching up? In particular, the size is normally different for every new controller.
