I have a PC with

• Ryzen 5500
• 16GB RAM
• RX 6650 XT graphics card
• B550 gen 3 msi motherboard (with 6 sata ports)
• 120GB SSD (currently what it boots windows off of)
• 250GB SSD
• 2TB HDD
• 8TB HDD

Is it possible to grab a 64GB usb stick, throw some kind of NAS OS onto it (I’ve heard of unraid, truenas), create a setup where if the USB stick is plugged in the PC will boot to NAS OS and ideally using 3x 8TB HDDs in RAID 5. If USB stick is not plugged in, then booting as normal into windows and use the 120GB SSD, 250GB SSD, and 2TB HDD for gaming purposes?

I’m aware booting off USB stick may suck, so I’ll probably end up using one of the SSDs as the NAS OS boot drive instead - just curious how viable it is to use a single pc as two different computers

Thanks!
