The difference might be caused by internal block size,
which kernel optimizes depending on the device size alignment.
The smaller the block size, the larger the number of I/Os sent
to the device (when you read/write /dev/something).
So you might want to check the block size ("blockdev --getbsz")
and see if it's related to your case.
