SMART works without any problems for me. Enclosures are 1* Raidsonic ICY Box IB-3640SU3 and 1* Buffalo Station (ancient).
I have a 4big Quadra from Lacie (old part) and eSata works wonderfully. The thing even has a Raid5 on it and has had no problems with it so far. Unfortunately, I can't say anything about SMART.
