Some fake micro SD cards are simply binned chips that didn’t pass quality control so you’re getting a product that was originally meant to be thrown away… How can I avoid getting scammed? Then, after you fill it up to a certain point, say 8GB, the files after that point get corrupted or worse yet, everything gets corrupted. It’s like getting a 32GB microSD card which shows up as a normal 32GB card even with the amount of space lost when you format it. Unfortunately, one can find a great deal of fake microSD cards on eBay and some other online websites which, not surprisingly, mostly come from China.įake, you say? By fake, I mean that the microSD cards don’t have their proper capacity because they’re in reality smaller micro SD cards with a messed up firmware to give the illusion of more space. I have tried to google the ‘problem’ hoping to find similar cases, but no luck there.The prospect of getting a decent capacity microSD for a little more than a cup of coffee may seem great but in reality, it really isn’t. So what’s going on with FakeFlashTest? Is the message a false positive or is there something fishy about my cards? Anyone got a clue? So the cards work fine, the read/write performance is good too, except for bad 4K writes on one of them. I’ve also tried loading them up with 64gb worth of media and all the media seems to work fine. The thing is though, both cards pass h2testw with a write speed of 40MB/s & read speed of 80MB/s for the entire 64gb of storage.ĬrystalDiskMark benchmarks results are also great, except for one of the cards that has extremely bad random 4k writes, like 0.008 MB/s. I get a similar message from the other card, only from 1000’ishMiB to 37,902.0MiB. I always like to test my sd cards before I put them to use, so I run FakeFlashTest, H2testw & CrystalDiskMark to benchmark them.īAD MEMORY from sector 107859 (52.0MiB) to sector 77624659 (37,902.0Mib) I’ve even bought from this seller before without issues.

I recently bought two 64gb micro sd cards (SanDisk Ultra) from Ebay, the seller’s called ‘atmemory’, he has an excellent rating & many sales. I am hoping someone might understand what’s going on here and be able to explain to me if my cards are fine or not.
