When i compare it to my 5TB Elements drive, it shows this 8TB drive is much faster in random reads & writes (5TB one does somewhere around 2MB/s 4K where 8TB one does like 26MB/s reads and 4.5MB/s writes). It means (per my knowledge) that the 8TB one can do more small operations per the time interval. I think it does it for the cost of a little bit more noisy reads or writes).
