This is not an identical test as the data is just read then disposed of.
You could have a look at the wikipedia article on device bandwidths and 
do some sums
http://en.wikipedia.org/wiki/List_of_device_bandwidths
I'd check things like the DMA mode of the drive, the backplane bus and 
card types and versions, the north and south bridge types, the memory 
speed and type, the FSB speed etc., to see what the theoretical capacity 
is and record the actual throughput to see if it approaches those 
values. I'm not sure what hardware you have, so you'll have to consider 
the data's path yourself.
