howto power hdd via usb3 on rockpro64

[tllim]

Hi,
I am looking what I would need to build a NAS with a large 4tb sata hdd 3,5" using usb3 only

My setup would be:
1- A rockpro64 with 12v adapter
2- A powercable for sata drive  https://store.pine64.org/product/rockpro...ta-drives/
3- an external hdd drive 12v 4 tb 

I do not need ssd speed so using usb3 should work.

4- so  I was considering using the usb3 to sata adapter for the rock64 https://store.pine64.org/product/usb-3-0...with-uasp/

However, it is not clear to me if this usb3 cable is compatible with using the powercable for sata drive of the rockpro64?

Can anybody explain what I need to power a hdd sata drive via the usb port of the rockpro64 please?

Thanks!

You cannot combine both cables to operate external HDD drive, this due to only Sata Cable already occupied both Data and power port. However, if you plan to power +12V to your external HDD (assume is 3.5" type), just plug in 12V 2Aor above power thru the 5525 DC Jack at the side of the Sata power cable.
