Before I go any further: yes, “Sansumg” is misspelled. No, it’s not a typo. This is one of the first cards that I bought off of AliExpress, and I spotted the misspelling immediately — in fact, it was the whole reason I ordered it. The makers of this card even went so far as to try to make their logo look like Samsung’s — taking Samsung’s logo and switching the “M” and “N” around. Because of this, I have them marked as “knockoffs” in my list.
On the performance front: being fake flash, this card did about as abysmally as I expected on its performance tests — maybe even worse. All performance metrics were in the bottom 9% of all cards I’ve tested (as of the time of this writing).
This card carries the U3, V30, and A2 marks. Unsurprisingly, performance was good enough to qualify for none of them.
On the endurance front: this card was doing just fine until round 1,971, when it suddenly stopped responding to commands.
