I know when I purchased this item that it is possible it would be a fake card, so upon receiving the item I tested by writing files to the card. Unfortunately, anything larger than 16 GB would result “corrupted file” error. This card is labeled as a 128 gb and indentified by my pc of having capacity of 124gb , the real capacity is probably 16gb, definitely less than 64gb. The seller was jayspree.
It's says I bought the 128 gb. When it arrived it said 256 gb on thr card. After formatting it, it said i had 269 gb availible. But when i upload files onto it, it only handles 6 gb before saying not enought memory
