Configuration with RAID0

Hello. I am just looking for feedback on my setup. Not looking for howto. I can figure that out for myself.

My PC has 256g SSD and 2x 500g HDD. My thought was to raid0 (mdadm) the hdds and use for /home and swap while sdd is for the rest. I have an external nas I can use for backing up, so not worried about data safety. Just speed. I am the only user.  How dumb is this?

Note: I am returning to Arch after a bit of a break. System is currently win10 and I will be removing it all. Already saved important data. Most what I have found is either old or someone trying to raid SDDs which I have learned does not have much benefits. But my understanding is using hdds should.

Re: Configuration with RAID0

many parts of /home (especially dotfiles) benefit a lot from ssd speed .
I suggest to use the raid for storing large things like movies , git tree clones etc.

swap benefits from ssd speed, but it also needs room .
You could have a smallish swap on the ssd and larger ones on the raid to combine speed and size .

(Most of the time my swap use is between 0 and 4 Gib, but I had to allocate 24 Gib to prevent oom issues from crashing my gui during some tasks)

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
