I've never come across a consumer 2.5" SATA device that uses 12V. I've been plugging them into my laptop's USB ports for a couple of decades or so now with no 12V rail in sight No issues. And for 3.5" SATA devices, I am smart enough to know to use an external power supply. Lack of on-board 12V has never stopped me. It has also never stopped anyone with a conventional ATX PC on their desk (oh noes! external power again!) Whatever the reason is to not include a SATA port, power ain't it.
