About real capacity 32GB = approximately 28GB-30GB 64GB = approximately 58GB-60GB 128GB = approximately 115GB-119GB 256GB = approximately 230GB-238GB 512GB = approximately 460GB-475GB This is calculation difference between manufacturer and your PC, please Google 'Memory card capacity' to get more information. Your PC says 1GB = 1.073741824 Billion bytes where Market Defines 1 GB = 1.00 Billion bytes.The pursuit of the perfect person is not recommended to buy. We promise only sale 100% Original the SanDisk SD memory card !

According to companies internal testing, the speed will be based on the use of equipment, interfaces, and the use of different factors such as environmental change. Steps to verify the capacity and speed of the memory card (1). Please use quality USB 3.0 card reader to verify all memory card by H2testw on PC. Real memory card should pass H2testw with no error. (2). Please don't use cheap card reader to test SD card, speed of SD card will be reduced by low quality card reader. (3). SD memory card speed is greatly affected by card reader and the capacity you choose , USB port etc. Low quality device will 100% slow down card speed,1MB=1000KB
