To make it easier for you to understand the performance of the product, We filmed a video to test the true capacity and speed of the memory card.
Please use the computer to watch, if you can not see the content, please adjust the clarity to 720p OR 1080P
The video was originally about two hours long, has been reduced to five minutes.
These memory CARDS are U3 high speed CARDS.Much faster than a CLASS 10/U1 memory card.Suitable for high quality mobile phones or mobile devices.
────────────────────────────── About Real Capacity ──────────────────────────────
16GB = Approximately 14GB-15GB 32GB = Approximately 28GB-30GB 64GB = Approximately 58GB-60GB 128GB = Approximately 115GB-120GB This is calculation difference between manufacturer and your PC, please Google "Memory card capacity" to get more information. Please Well Note. Thank you so much. ─────────────────────────────────── About Speed ─────────────────────────────── 16GB-Class 10-SDHC 32GB-Class 10-SDHC 64GB-Class 10-SDXC 128GB-Class 10-SDXC Class10 U1: Read speed around 15-30MB/S ,Write speed around 9-12MB/S Class10 U3: Read speed around 30-260MB/S ,Write speed around 30-150MB/S
The above data were obtained through the laboratory.
The test report shown in the picture is the test result of the local computer.
Same size, faster speed!!!!!! UHS3's unique fast reading and writing ability can meet all kinds of 2K/4K digital video device recording and playing.
Steps to verify the Capacity and Speed of the memory card: (1). Please use Good quality USB 3.0/2.0 card reader to verify all memory card by H2testw on PC. Real memory card should pass H2testw with no error.(please Google "H2testw" to get more information.) (2).
