Device sizes vary according to manufacturer and model. 3% is not uncommon. Here's one actual "1GB" USB2.0 flash memory device that I use [from syslog, /var/log/messages]: usb 1-9: New USB device found, idVendor=154b, idProduct=0005 sd 9:0:0:0: [sdc] 2015232 512-byte logical blocks: (1.03 GB/984 MiB) That's 30MB (3%) more capacity than labeled. Here's a "4GB" device: usb 1-9: New USB device found, idVendor=154b, idProduct=000f sd 13:0:0:0: [sdc] 8060928 512-byte logical blocks: (4.12 GB/3.84 GiB) That's 127MB (3.2%) more capacity than labeled. Here's a "8GB" device: usb 1-9: New USB device found, idVendor=13fe, idProduct=5100 sd 11:0:0:0: [sdc] 15466496 512-byte logical blocks: (7.91 GB/7.37 GiB) That's 81MB (1%) less capacity than labeled. Here's a "16GB" device: usb 1-10: New USB device found, idVendor=13fe, idProduct=5200 sd 10:0:0:0: [sdc] 30283008 512-byte logical blocks: (15.5 GB/14.4 GiB) That's 495MB (3.1%) less capacity than labeled.
