Yes, they do in nibbles (4 bits), but it's only mandatory for high speed cards.
And there's no benefit in my case, I just read and write bytes.
The serial SPI transfer is achieved at very high speeds (from the amiga point of view), so you have your byte transmitted and/or received faster than the cpu can get them from the main memory.

In case you're interested:
