1GB flash drives are still 1GB today.
>256 GB is now common, which would make that petabyte less than 1 football field. (It's only 4096 such drives.)
If we're completely changing what we're using for scale, you can fit a petabyte on ~10 100TB drives, which is like 3% the length of an olympic swimming pool.
is it supposed to be actual football one or the field for handegg?
As a side-note Canadian Gridiron football uses a longer field than American Gridiron football, though (measuring between the goal lines) still slightly shorter than a typical Association Football pitch.
Australian Rules Football is on a field typically longer even than an Association Football pitch, though I don't believe there is a regulation limiting the size.
