Android and the 64 billion bytes question.

[Hetz Ben Hamo]

Hi,

The ExFAT was invented by Microsoft specifically for such a removable
storage and support for flash cards with this sizes (it supports up to 64
ZB). Its fully supported under Android (Samsung wrote the kernel module, so
there's a native support for it), and you can grab the kernel module from
here:
https://github.com/dorimanx/exfat-nofuse

You can use ext3/ext4 (ext2 is a dog slow on SD) but then you'll have the
overhead of journaling, and you won't have any compatibility with any
Windows/Mac, in case you want to stick your card into such systems.

תודה,
