A single hard drive will see no performance boost on a 66/64 slot, as the drive itself scarcely begins to touch the performance of a 33/32 slot.
So it wouldn't really matter where the drive goes. It's about what would be convenient for you.
Depends on the controller my friend. You get more then just total bandwidth. With 64/66mhx its actually moving data faster sooner. You ramp up faster IF THE CONTROLLER is made to handle it. Your peak score as far as transfer rate doesn not change but it moves data faster through the whole range often.
Great example. My HPT 4ch 1540 was advertised as 66mhz capable and the box says it is but now HPT changed their mind and say its not but.... In the MSI-k7d with it stripped down and hardly any cards in to jack with each other...
On atto on the first line for instance in a 64/66 slot I hit the same on writes bascialy with a two drive raid-0 but the reads are almost doubled. From 7000 to 12000 on the first line alone. with it just being slipped out of the 32/33 to a 64/66. No your top scores on atto won't change as total transfer rate didnt change much but stuff like Sandra show a jump. And teh low end on ATTO will change often also. 64/66mhz has more use in real life then your seeing so far!
My high dolalr scsi controllers iwth teh risc cpu's and cache will run in a 32/33 slot too but not at nearly the speed even for a single drive. Its strictly controller dependent
