if you have a beige g3 with16.7 MB/sec max or a blue&white with 33MB/sec max you'll definitely notice, as SINGLE drvies today perform better than that. however if you have a G4 with 66MB/sec or even the new with 100MB/sec you wont notice a big difference with a single drives, as only the cache bursts would be faster on a faster bus. sustained read or write rates will not be affected, as a single drive is not likely going to produce more than 66MB/sec sustained.
If you want to run a RAID, hardware RAID adapters are the only way to go anyway.
How big the difference is for dual drive setups. i don't know, but probably also only marginal due to the way ATA handles master/slave configurations. (the slave always has lower system priority)

G-News
I've got a G4 466 with three drives:
-30GB (5400rpm)
-40GB (7200rpm)
-40GB (7200rpm)
My system shipped with an ATA 66 bus.
