This is a brand that I found while looking through microSD cards on AliExpress. Why is “Sansumg” in quotes? For starters, it fails my criteria for determining name-brand cards for a couple of reasons:
- The card came in retail packaging, but the packaging didn’t identify the vendor who sold the card.
- As far as I can tell, the brand doesn’t sell more than just microSD cards.
- I’m just gonna take a hot guess here and say that they don’t have a website.
- The card is fake flash.
And, it does meet my criteria for knockoff cards, for one primary reason: the name is substantially similar to a well-known brand name (Samsung, in case you haven’t figured it out). So…into the knockoff bin you go!
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.
