Ching do you know any 4-bay enclosure uses ASMedia chipset?
So far only ASMedia chipset would behave what I want:
1. Don't sleep the HDD by itself
2. Spindown on eject
3. Report power mode properly
This UNITEK Y-1039B adapter I bought uses ASM1153E

It can report power mode properly, which is a very important feature I want not to wake standby HDD.

Device is in STANDBY mode, exit(2)
Another Orico HDD dock I own which uses JMS561U don't report power mode properly.
