It was important for me that my Smart TV from Samsung accepted this USB stick. In an experiment conducted by my read-write test USB 2.0 26 Mbit have been identified for reading and 24 Mb for writing. The televisions used for this USB Stick to USB recording is a Samsung UE46F6470, so therefore is very much likely that the F-Series hereby wonderfully get along. An external hard drive 2.5 inch without own power also worked, however, bothered me the noise when recording when you are not switched on the television, for example. When USB stick, there is no noise. Good price - Good performance - buy recommendation from me.
