Was immediately recognized by my SGS4 and can be described and read without problems. Movies in FHD can be easily viewed directly from the stick. I have done no benchmark test because I find it interesting anyway what the device Provides maximum. Interestingly I find a reality check. Have pushed the overall size of 5.5 GB on the drive 5 files. This has 6 minutes and 50 seconds. lasted. Power 13.4 Mb / s on average. The reading from the drive is much faster. 5.5 Gb in 50 Sec. Power 110MB / s.
Could of course be faster when writing, but I admit still 5 *
