Hi, i've an Hdd of 1TB and i would like to use it as a storage for my orange pi 5. I would like to install armbian and boot directly from the Hdd the operating system. I need only to buy the adaptor for sata interface.

Before to buy it i've read some posts and also watched this video https://www.youtube.com/watch?v=Z5-sZt_O51w&pp=ygUZb3JhbmdlIHBpIDUgYm9vdCBmcm9tIHVzYg%3D%3D

and this guy was not able to boot the orange pi directly from the Hdd because the adaptor was creating some problem.

1) I would like to ask you if someone knows if in this months this problem was been resolved or not

2) If it is not yet solved, i would like to install the OS and boot it from the MicroSD card and use the Hdd with the adaptor as a storage (like a big usb stick), does in this way the Hdd will be visible and would i be able to use it?

 

You do have a way to power your HDD do you? Or is it an SSD?
A sata adapter only powers 2.5" devices. If it's 3.5" HDD then you need 12V. 
I would advice not to boot from HDD. If something goes wrong with the image on an sd-card then you just replace the sd-card without loosing anything from the HDD. 
Do use a good sd-card. Hard drives also aren't super fast, so no real speed benifit in using that. 
 

If ssd, self powered USB hub works. Although I'd just mount it and keep booting off the SD.
