ext2fs will quite happily handle that situation (in fact its not an atypical pattern of I/O on a big multiuser box - consider someone doing a download as another user does an rm -r.
ext2fs tries to grab linear chunks of disk and divides the disk into cylinder groups to also help to maintain locality. The BSD ffs papers [McKusik et al] describe this sort of stuff well.
