This will be the space taken up by the superblocks, presumably. This isn't the "5% reserved" space, which for that drive would be about 93.18 GiB. I think the problem is that ext4 makes copies of it's superblock every so often throughout a drive. The bigger the drive, the more copies it makes. You could try formatting as XFS or BtrFS and see if the space used is any better. > > Thus NTFS reported using about 240 times less space then Ext4 file > system.
