Decipher the Code of MicroSD XC Cards model Numbers of Extreme and extreme pro cards?

I have found thousands of users all asking the same exact questions, but there doesn’t seem to be any definitive answers from SanDisk as to what the difference between their part numbers are.

 It is very unclear what the differences are between various Sandisk MicroSD cards.

The 64GB MicroSD Extreme Pro and Extreme a has several variants which all show “up to 30MB/s”:

Extreme Pro  64GB microSDXC Class 10 / UHS-1 U3 A1 100 Mb/s    SDSQXVF-064G-GN6MA

Extreme Pro 64GB microSDXC Class 10 / UHS-1 U3 A1 90Mb/s       SDSQXAF-064G-GN6MA

Extreme Plus 64GB microSDXC Class 10 / UHS-1 U3  A1                   SDSQXWG-064G-ANCMA



U3 64GB microSDXC Class 6

Does anyone know what the difference between the “SDSD    QXVF-064G” and “SDSD   QXAF-064G”  “SDSQ  XWG-064G”  part numbers means?

Does anyone know what the difference between the

“GN6MA” and “ANCMA”  “G46A” part numbers mean?

I have read in various forums that:

1 - The  Extreme Plus  and Extrme Pro has better Random Read Write speed and gives more than the specified speed

  1. How and  by which to diffrentiate with codes  printed that the card is Ultra/Ultra Plus/Extreme/ Extreme Plus/ Extreme Pro ?

  2. The class A1 is better for random read-write than A2 the class 10. Is this true?

4 - How to find the packed card inside and outside configration  package is matched

5.  How to differentaite between fake and original sandisk cards

6 How to  check the serial number or model number  with sandisk any link or site or app which we can confirm without buying   its validity  its waranty and its origanality
