This trick the operating system into thinking there is 1 TB of storage, and by all accounts moving 1 TB of data (which I can’t imagine the time that would take on USB 2.0) will seemingly work. The write process may very well show the full amount, however the drive has a background program that actually re-writes over the original. The problem with some drives, is they may seem legitimate when used. Considering the cost of current 1 TB thumb drives are several hundred dollars, the saying of “If it looks too good to be true, it probably is” comes to mind. I highly doubted that the drive was legitimate, especially since there were no reviews. The 1TB drive is the one that really stood out to me as it had a very surprising price: $20. There I found a USB 2.0 thumb drive for sale in two capacities: 512MB and 1TB. I have tried to google the ‘problem’ hoping to find similar cases, but no luck there.As I browsed the net for high-capacity thumb drives, I came upon a curious site called. 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.
