Work fine with the 630 receivers.
And they work fine even if have their own power source separate from the receiver itself
At least the ones I've tried from Startech, but they are only single drive docks
I replaced the stock SATA cable with a 24 inch one from local computer store
**530 receivers have issues with docks ,unless connected and powered from the receiver itself. That is they have to power up and down in sync with the 530 receiver**
