Ah so your setup is almost exactly as what I had planned :D (I’ll use 1 SSD instead of 2 though, to be used as boot drive). I haven’t made the box yet, probably in a few months.
Thank you for the reply!
Please do post your updates somewhere in this thread, I’m sure they’ll come in handy when I start building my box.
I recently wrote a blog post about the new NAS I built myself and why I didn’t choose for a RPI 4. https://jeroenpelgrims.com/diy-nas/
I think it terms of price it won’t be much more expensive than an RPI NAS, but you’ll get more performance and stability.
If you don’t care about power usage and/or connecting stuff through USB you can also buy some older hardware instead.
