I am comparing the 9-gig drives with the 4-gig drives of the same
generation.  I tried a 9-gig drives in various places and the result was
always a slow machine.  I talked to a few other people and they said
they had experienced similar poor performance.

Calculating crudely:

If a 9-gig drive is 40% slower than a 4-gig drive based on its seek and
latency specs, and if it is also 40% slower than two 4-gig drives
because they have two spindles, then the 9-gig drive will be 0.6 * 0.6 =
0.36 times as fact as two 4-gig drives.
