Hello world.

Last week I visited a friend who has got a 600MB SIEMENS hard disk.
We installed it with different controllers ( WD7000FAAST2 and AHA1542B ).
Surprisingly we measured different seek times with some standard test programs!
I don't exactly remember but i think the 'track-to-track' ( average )
times were 
3.3ms ( 13.3ms ) for the WD and 6.7ms ( 16.7 ) for the AHA.

HOW CAN THIS BE ???

Note: The only things we've changed were the controllers!

Thanx in advance,

RAINER.
