Very good question. And the answer is simplicity.
f3 is targeted at detected "fake" flash disks which pretend to be larger
than they are. There is a lot of code around that, handling file system
and detecting flash disks and stuff like that. Yes, f3 too writes a
random sequence and checks it. But then tries to locate the maximum
valid size and so on.
f3 is 3992 lines of C code according to my loc-counting tool.
disk-filltest is 380 lines and does not try to do anything fancy.
Best,
Timo
