The data can be read quickly while the 32GB flash drive (> 100MB / s) but only very very slowly be written to it (measuring program varied between 32 MB / s and 5 MB / s, average was about 7 MB / s). Since so many USB2-Stick is faster when writing. The stick is suitable in my view, only for people who write data once it but several times read it. PS: Delivery by Amazon was also delayed in this case. 5 days for Amazon Prime articles that are in stock, I have not previously experienced. Probably the stick goes back due to the low write speed ...
