I have been using SP products for a long time. I felt the first problems on the SD card, which was not detected on the camera. Now I managed to buy an 8GB flash drive. I noticed that sometimes the files copied from the flash drive turned out to be broken. How many times has this crap let me down. Here is the log made by Flash Drive/Card Tester: 00:33:082022 - Completed "Reading and comparing data" for drive N: 7680MB, "UFD 2.0, Silicon-Power8G, 1100, ", 512b 00:33:082022 - Tested total 7680.999MB in 0:09:00 with 1420229MB/s 00:33:082022 - Total errors: Read fatal=0, Read recoverable=0; Write fatal=0, Write recoverable=0; comparison=15
