This memory card is bought by me in the local market store. I am using this memory card for my mobile. As this is a 64 GB memory card. We can bulk store the data in this memory card. Actual memory in this memory card is about 59 GB. But now this memory card has an issue. It is not working. All the data is erased in this. I found this memory card not a reliable and durable product. So one be careful before buying this product. Overall We should backup all the data in this memory card to our another storage device for security purpose.
