Has anyone done any testing on if paying the premium for UHS-II SD Card is worth it for the WiiU. Obviously speed Class 10 is a must. Just wondering if theres any testing or homebrew that can measure this. really curious to know if I can increase load times by paying a bit more. or pay the same and just get a bigger SD Card. UHS-II was designed for 4K video recording and the bitrates for it. I could get a UHS-II 64GB SD Card that Reads at about 144MB/s and writes at 78MB/s, which is hella lot faster than the results of most UHS-I SD card reviews. But is it worth the extra cost? especially if the bus speed on the WiiU isnt even UHS-II compliant. Side-Q: Is there a max cap. on the SD Card size the WiiU can see? Edit: cant edit the title, just realized UHS and U# are two different ratings. UHS is Bus Speed. U# is a Speed Class...higher than the older Speed Class "C#"
