My old Stealth 64GB had actual capacity 59GiB according to gparted. My new one has 57.73GiB. In fact until I recreated the partition table it had even less than that. Keep in mind this is the capacity of the block device as reported by linux, It's not the capacity of the filesystem. What gives? Does the new flash drive have smaller memory chips than the old one? Or is the wear-leveling reserving more of the space on the chips in the newer version of this flash drive?
