The problem isn't read-ahead of the data in the file. The problem is that there is absolutely no read-ahead of the FAT. Only the one sector of the FAT that is currently needed will be read.
I don't think that this changed very much between 1.2 and 1.3.x, because the access to mounted floppies was always slow since 0.99.x (which is why I used mtools most time).
