looks like same manfid and controller like the first filemate card in your list
Ah, I wondered about this. I also had a Sandisk-labelled card with the same controller and name "LEXAR", so this is probably the same hardware. Sandisk also confirmed to me that the card I had was not an authentic Sandisk card.
interesting. so this is probably a fake? but the same 8GB card has similar values but a different manfid and oemid..
-> ok, definitively 8MiB erase-block size
This is not a strong indication, all you can see from this is that the first write was slower, but that can be because it did a garbage-collection before.
ok, i see
No. What happens is that every write access is a whole erase block,

so this should be always the case then, that writing with the exact erase-block size remains fast also with many concurrent blocks
