On a side note, is there any benefit to storing applications on my SD Card?
Well when you move an App to Storage it is really moving it to /mnt/sdcard/.android/ (hidden folder, usually with a tmpfs mount hiding the contents so people can't mess with app data
) , this is still the tablet memory since Samsung just uses a big partition (at least on my device), so whether its under /data/data/(app) or if its under /mnt/sdcard/.android it won't matter since it's still the same space on the same partition, really no benefit there. (though on some other devices the /data/data/ and /mnt/sdcard might have separate partitions and it can help free up space ..etc , it varies from device to device)
if you want to use an external sdcard to store app data (like big obb files for games ..etc) you will most likely need root (at least until android 5 comes out) and use a program like "Folder Mount" to redirect the mount points to the external sdcard..
for example you can make symbolic links ie: "/mnt/sdcard/Android/obb/com.rockstargames.gtavc" will redirect to "/mnt/extSdCard/Android/obb/com.rockstargames.gtavc" , this way the big content will reside on the external card, and the apps will still be installed on the internal storage but take up much less space.
