This should serve well. I'm using a 4-port version to power 2.5" HDDs

2025, update.

With usb to sata adapters like these, they have DC power jack for external power.

Here you can use DC barrel jack splitter like this one.

This is as easy as it's gonna get. One DC adapter will power all.

Thanks. I will use it so.

If you have a Rpi 5, you can use this like this.

Those DC Jacks are 12v only. ie.) For 3.5 inch HDDs.

You might not find any benefit for 2.5 HDDs or SSDs.

Cheers

Good call, I will test and report, if we use 5V adapter will the SSD switch to external power or not.
