I bought transcend flash 16 gb 4 years. when something went wrong i opened it due to gurantee was years ago canceled. So when i opened it i founded sandisk chip instead of transcend chip.
That means that mine flash was fake or what?
No, not a fake. The memory chips themselves are often made by a different company than the company name on the casing.
It all depends what memory chips were available at the factory where the pen drive was made.
