Unfortunately, far too slow. Have tested the stick as a 64GB version (19.27) and wanted to use it as storage for my Samsung SmartTV. Unpacked (which ne quite torment was) connected to the TV and can be formatted directly on exFAT. Then the disappointment (see product image 64GB). This USB stick does not even provides the minimum requirement for TimeShift or even shots. The tested speeds are on TV: Be 2,2Mbps | Read 3.0 Mbps. I tested the stick then they're on a PC with h2testw of c't. Previously, I formatted the drive to NTFS.

The read speed is okay but the write speed lets me grow gray hair. Nearly three (!!!) hours to the stick completely to fill? That will not do ..! I have a feeling that the stick reacts very sluggish. Two were given by reformatting Windows with an error message. This stick is completely useless for me and goes back.
