I have a raspberry pi model 4b, with the official 15w power supply(5.1v/3a). I have a 240gb CS900 SATA SSD, which I want to use as the boot drive, and two 5200RPM HDDs. I plan to use them for a home samba share, to store photo backups, and device backups.
I bought a sabrent sata enclosure, however I discovered this has issues outputting IO ERROR when trying to boot (likely due to lack of power or some quirk with UASP) and requires UASP to be disabled from this blog, so I opted to return this and get one that is known to work for the pi 4b, UGREEN sata enclosure mentioned in the blog.
Assuming this new enclosure works (directly connected to the pi), I believe I will require a powered usb hub to drive the other two hard drives. Keeping it on brand, I have decided to go for the raspberry pi hub, but I am unsure of which power supply to use for it. I am considering using the official 15w that I have currently for the hub, and buying the argon power supply which provides 5.25v/3.5a over the standard 5.1v/3a PSU to power the raspberry pi. Alternatively I could just pick up another official 15w raspberry pi power supply.
Alternatively, I was looking at the sabrent powered usb hub, which was used in the previously mentioned article, and comes with its own PSU providing 5v/2.5a.
Both options come out to around the same price, so would it be more beneficial to get the pi hub with the argon power supply 18w , an official raspberry pi 15w or the just get sabrent powered hub?
