IMPORTANT!
The built in this stick controller is obviously optimized for the NTFS file system with 4KB cluster size !!!
If you FAT32 / exFAT or NTFS cluster size over 4KB used with interrupts the write speed with smaller files (MP3s) together catastrophic.
In addition, he constantly puts the store a short pauses that you noticed both in copy-DALOG and on the number of LED blinks.
ATTENTION !!!
This stick has problems with a number of extension cords and cables from the front USB ports.
This shows itself in that file when you save massively damaged without there being an error message!
You notice it until later when files are destroyed, music or video files have dropouts or compressed archives have CRC errors.
The error occurred while my example with a "Renesas PD720200" USB 3 controller in conjunction with the "Logilink CU0035" USB 3 cable with docking station on.
Directly to the rear USB ports on the other hand there was with no USB3 controller problems.
Something I have never experienced in any other drive.
An USB 2 on the other hand this problem occurred not on.
