Hello,
I purchased the memory cards of the Samsung brand in the AliExpress online store (with delivery from China).
Cards model "Samsung MicroSD EVO +" in the volume of 64 and 256 Gb.
On receipt of this products - they turned out to be a fake (counterfeit).
The following characteristics do not match original:
The country of production (Taiwan)
The color of the microSD card (black)
a specially programmed controller is installed on the card that reports the above volume, but the real volume of both cards is 16 GB, the read / write speed is 5 Mb / sec, as tested by H2testw v1.4.
However, the seller sent the cards in their original packaging, and the holograms on the package are passing the test on Samsung web-site
https: (slash)(slash) support-cn (dot) samsung (dot) com (slash) product_validation/productverification/card_memory.html
The seller has also provided the authorization file from the samsung representative office in China / purchase invoice to proved the item was original
(most likely the cards were actually bought, but resold inside the country without packaging, and the package was used to sent a fake cards).
AliExpress asks for a formal response from Samsung office regarding the originality of these cards:
"We would like you to provide counter evidences as following within 7 calendar days: the official inspection statement from the brand owner."


Video of unpackaging:
www (dot) youtube (dot) com (slash) watch?v=3s84827ks-o&feature=youtu.be

Black side of the microsd card can be seen on the video at 222 seconds.

The data from h2testw application for 256Gb card:
Warning: Only 255991 of 255992 MByte tested.
The media is likely to be defective.
16.1 GByte OK (33799991 sectors)

First error at offset: 0x0000000406206e00
Expected: 0x0000000406206e00

H2testw version 1.3
Writing speed: 9.28 MByte/s
Reading speed: 6.73 MByte/s

Where i can get such official inspection statement (over the internet, since there is no samsung office in my city)? I can take additional pictures if needed.
Some of the other buyers on AliExpress has noted that they received such statement from Samsung representatives:
"Samsung confirm the case.. Black card from EVO means its a fake card (it should be white)"
