There are pci boards that let you hook up 4 sata ports to the pci3 on a raspberry pi 5. The drives will be a large part of the power draw, so if you want low power, going for 2 drives is probably better. That probably gets you into the 20-30 watt range

for 10+ sata ports you might as well get an x86 motherboard as it's going to draw lots of power anyway

Unless you plan to power down most of the drives most of the time

I do. Read my other comments.

		Yeah, it looks like you have somewhat niche requirements and would need to build your own hardware and software. To run 10+ sata drives you'll either need to take a lot of care they're not spinning up at the same time, or getting used in parallel, or you'll need to dimension your power supply to cope. A beefy power supply will have a higher idle draw making the focus on getting the whole system idle down to 5w pretty hard

rpi sux for longevity - be prepared to mirror and replace the SD card often

		I've never had this be an issue. If it were an issue, you could probably put just /boot on the sd card and run the system off one of the real disks
