How Much Usable Space For Different Formats - FAT32, exFAT, NTFS

Overview When formatting flashdrives or whatever....what is the best format for maximizing space on the device.  We tried a 32GB Kingston G3 traveller and formated it for FAT32, exFAT, and NTFS.


It really did not make too much of a difference.  The exFAT seemed to have the maximum of free space and the NTFS had the maximum of overall space.  Overall space includes both the unusable overhead space and the actual free space.  It seems that exFAT does not use a lot of overhead space.

exFAT allows for the maximum free usable space.
