This is ofcourse a totally unexpected results (you should think off the
opposite).
Your ATA disk is lying about disk caching being turned off. Assuming
each insert is in a separate transaction, then it's not going to do
10,000 / 6 = 1667 transactions/sec - that's faster than it's rotational
speed.
Funny is that the select time is the same for both machines.
Because you're limited by the speed to read from RAM.
By the way - these sort of tests are pretty much meaningless in any
practical terms.
