I appreciate that you have tested this drive powered directly from the Pi and worked. However, you also recommend to power it independently using a USB HUB. Please can you recommend such a hub from your own stock. Also I gather that an additional cable would be needed? SOmething like the 'WDLabs - PiDrive cable'? (currently out of stock) Thanks
You will struggle to power two HDD's directly from the Pi's USB ports. A powered hub would be recommended.

Thanks for the response. Apologies if you have already answered this in the above: would running two HDDs still be fine powered only by the Pi? (Thinking of setting up redundant storage etc)

Firstly, with the Pi3, the USB ports output 1A now, so there really is no need for a powered HUB anymore, providing you have a decent 2.5A power supply for the Pi. However if you do want to use a HUB then ou have a couple of options.
1. Simply use a powered USB hub, like this one - https://www.modmypi.com/raspberry-pi/accessories-198/usb-hubs-204/10-port-usb-hub-5v-4a - No additional cable is required.
2. Use a USB Y splitter which splits the data and power lines, like this - https://www.modmypi.com/raspberry-pi/accessories-198/storage-and-hard-drives/wdlabs-pidrive-cable - Then you can use an additional micro USB power supply to directly power the HDD.
