I have an older model (N0028USU) of this dock, with usb 2.0, sata and one bay. I use it with a couple 1TB drives for backups and long term storage.
It works great, but there is a minor design flaw with the power switch, which is simple to fix. I don't know if this flaw exists with the models in this drop.
The power button hits the pcb, preventing full switch actuation. The fix is to simply file a flat spot on the button sufficient to clear the pcb, then super glue it to the switch post. You should also file a little more away to account for switch wobble, which is considerable. After this fix, it won't be a problem ever again.
BTW, the eject button on these is just an assist. You have to pull the drive out while using the eject button, otherwise you might break it.
