I found that out a long time ago when I set up my Raspberry PI4 based NAS.

It's the power draw.
On other Pi projects, I used multiple flash drives and had no problems.
But my NAS project used 2.5" SATA drives with SATA-to-USB adapters - which will certainly draw more power. And I couldn't get more than one to work directly connected. I ended up getting a powered USB hub for all 4 drives in my NAS.
