Actually, on newer boards that's a myth, modern controllers can support
whatever speed each device can run at.

[edit] "Lowest speed"
It is a common misconception that, if two devices of different speed
capabilities are on the same cable, both devices' data transfers will be
constrained to the speed of the slower device.

For all modern ATA host adapters this is not true, as modern ATA host
adapters support independent device timing. This allows each device on
the cable to transfer data at its own best speed. Even with older
adapters without independent timing, this effect only applies to the
data transfer phase of a read or write operation. This is usually the
shortest part of a complete read or write operation.[18]
