@OldSchool Did you research if this is actually necessary? I used my 250 GB Samsung EVO 840 connected with an SATA-to-USB adapter to one of the USB2 ports of my Pi 3B (without +) for over two years without any problems, and now its connected to my new Pi 4B Rev 1.2 via USB3 for a month, again without any issues.

What problems exactly do you expect and where did you learn about them?

edit: I should mention that I also had/have a PacDrive LED controller for my 18 illuminated buttons and a wireless Mayflash Wii-U Pro gamepad adapter connected to the USB ports of both of my Pis, all of them without external power. The only somewhat funny "issue" I noticed is that the buttons flicker ever so slightly when the ssd is being accessed. 😊
