It's actually not all that difficult to saturate a 6Gb/s pathway with ZFS when there are multiple storage devices on the other end of that path. No single HDD today is going to come close to needing that full 6Gb/s, but put four or five of them hanging off that same path and that ultra-super highway starts looking pretty congested. Put SSDs on the other end and the 6Gb/s pathway is going to quickly become your bottleneck.
SATA and SAS are dedicated point-to-point interfaces so there is no additive bottleneck with more drives as long as the devices are directly connected.
