The 16GB memory card slips easily into a smartphone with Android operating system (in this case: LG L70) used with the Firefox OS, but also in the Alcatel One Touch. The memory will be displayed perfectly and copying and moving files goes smoothly and relatively quickly: 100 MB from the computer to the memory card in 12 seconds, 100MB move from internal memory to memory card in 17 seconds.
16 GB of storage should it for mp3s, etc. also be videos, photos already, particularly in smartphones, which have only a small internal memory as the two I tested. I have on other mobile phones also for years the memory cards from SanDisk, which also exist in the Test of Time. Solid and well. Also, the price-performance ratio.
