Various speed (class 6 or class 10)
by PC user on 8/10/2012
Somehow, this 64G microSDXC (performs as microSDHC) card comes with various speeds, either class 6 or class 10. I am not sure why. The one I pruchased came as class 10. However, as I did some research, class 6 is provided in other cases. Regardless, you can't control that. Meanwhile, the card behaves as other microSDHC cards. It can be read by card reader, camera and sandisk mp3 player with microSDHC expansion slot. I am suprised that the mp3 player can detect 64G (it is 59G aftter format) card. However, an important point is before you can use it, you need to format it. Unlike most SDHC or microSDHC card, this card is not automatically accessed by Windows. Windows sees this device but you can't access it right away. Windows asks you to format it. But when you try to format it via Window Explorer, it gives you an error. So, what is wrong? Not sure why, but you can format it via third party hard drive software. Either parition magic or Aomei Partition Assistant Home Edition would do the trick to format this card. I was able to format as FAT32. So, don't assume the card is bad if you can't format in Windows.
