Does the fact that each has a switch mean that you can just turn each of them off without doing "safely remove" or "eject" devices?

In a reply from SABRENT they say that for any "data storage" device the Windows "Remove Safely" should be used before activating a port button to "off". I would interpret that as a "must", if you are concerned about your data. Obviously you can simply hit the button for devices such as speakers, mouse, keyboard. But then, for those devices we usually just pulled the cord, right? ^_^

If I plug this into a 2.0 USB port on my CPU, will I still get the benefit of Sabrent's 3.0 speed? Or is it about time I update my motherboard? Thanks

@T. Freese: No. The nature of USB is that devices can not communicate among themselves. All communication goes through the host computer. So a pair of 3.0 devices sharing a hub attached to a 2.0 computer will communicate at 2.0 speeds.

What is the recommended ac adapter to use with this?

We recommend using this power adapter: B00MRGKPH8 "PS-5V4A" which will give you 5V 4A to powered an external Drives

I have 2 external hard drives: 1 is 500 GB, 1 is 2 TB. Both have their own power cords. Will they work with this hub?

yes they will, I have a 3 tb WD, a 2 tb Fatom,and a 1tb HP they all work fine, and and any thumb drive that I plug in syncs right up.Some of the thumb drives are usb 2.0 , no problem
