gstat more writes per seconds than there are seconds per write

[Ronald Klop]

Hello,

I'm confused by this output.
w/s = 5, but ms/w is 1108; how can I put 5 writes in a second if the  
average write takes more than a second?
Is my SD card super parallel? :-)

Sometimes the numbers are even higher.
