I have a Pi4 running Raid 1 NAS with two SSD drives, and an externally powered USB hub. Unfortunately, it crashes every 6 months or so and needs a power cycle. Haven't been able to track down why, but I also suspect a power supply issue.

Initially I naively tried to run the two drives right off the USB3 ports in the Pi, and that basically crashed within a day - but that is of course because I was exceeding the power draw. An external hub and supply helped, but didn't fully fix the issue.
