Keeti, thanks for your reply. I had searched for and read what you sent before. I re-reread it this time more carefully but still did not find anything about model numbers and specifically nothing about the one in which I inquired.

I suspect the model numbers differentiate between the version dates or possibly the manufacturing location or differing warranties for different markets.

For instance the latest one’s model number is SDSQXAV-1T00-GN6MA and has speeds up to 190 MB/s (versus 160 Mb/s for the ones I cited

) in tailored equipment even though they are all Sandisk Extreme 1TB, A2 U3 V30

This might be slightly older post but i shall update the difference i found for better insights into this (if there is another post about this, my apology since this is the only related one i found)

SDSQXA1
This is the standard A2 speed sd
Read speed - 160
Write speed - 90

SDSQXAV
This is SDSQXA1, enhanced with sandisk QuickFlow technology. This supposedly speeds up the sd card
Read speed - 190
Write speed - 130
This is more expensive
As of date of writing, this is about 20%~ more expensive from where i am. (111 vs 136)
