Why is it a waste though?

You're killing the read/write speeds on the card with FAT32 when compared to exFAT.

I have a 128GB card formatted exFAT and it works fine in my device.

I'm thinking it won't work stock, and needs to be enabled in kernel? Thats what the Verizon guys have to do. (FAT32 or enable exFAT in the kernel...)

I've never used anything but stock kernel.

exFAT is enabled by default. When you format the card in Settings - Storage, it formats the card exFAT.

Hmmm...:/ wonder why it doesn't for me. It'd make sense for it to work. When i put it in the phone and format it, it does format in extFAT, but the phone doesn't mount it like that...

So the phone formats it, but then won't mount it? That doesn't make any sense. Sounds like something isn't working right.

If the card is 32GB or below, that makes sense, but for XC cards, exFAT is the default format.

I'm seeing very poor R/W speeds from my card. It supposed to be a class 10, 64GB
http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1


In the Benchmark tool, it gets detected as the Internal SD card for some reason. But regardless, this card should be performing faster, IMHO.
5MB/s read and 4 MB/s write seems very slow. In fact, if I set my pictures to save to the SD card, it gives me a warning that my SD card is too slow.

I just tried formatting via the phone menu (Settings > Storage > Format SD Card), but still pretty slow.

Any thoughts on how to speed it up? Did I purchase a bum card?
