> Sure you could always use hard drives and SSDs with SATA to USB adapters, but you [...] can't RAID them together, at least not without some hacks. Why can't you RAID them together? The kernel doesn't care; all it wants to see are block devices. I recently recovered the files off a dead NAS by plugging the drives into USB adapters, and plugging those into a Raspberry Pi. RAID array assembled just fine.

Yes - on the rpi4s, you can enable booting from usb devices directly using raspi-config, although raspbian is only 32 bit, so I wound up having to do a weird dance of using raspbian to enable usb boot and then installing ubuntu on the drive to get a 64bit OS
FWIW Raspbian has a 64 bit version in beta https://downloads.raspberrypi.org/raspios_arm64/images/raspi... the base image is outdated but you can full-system update from that point. I'm the same way though, I just use a more typical distro unless there is something I need the standard toolset for.
Edit: although giving it a second glance, it looks like there’ve been a few updates: https://downloads.raspberrypi.org/raspios_arm64/images/
Has the situation around booting from a USB-drive bettered for the Raspberry pi 4? Last time I tried, I couldn't figure out how to actually make it work.

Note that Raspberry Pi OS also has a 64-bit beta version, and it's been extremely stable for me for months now.

Many applications won't allow the RAID to be set up over USB devices (e.g. Open Media Vault, IIRC), because software RAID over USB is prone to flakiness.
