I have a laptop setup similar. it had space for a 2.5 ssd and a nvme so zfs
*RAID-Z1* worked well. They are not the same speed but zfs raid 1 was worth
it to me and still very fast for my uses.
I currently have it *RAID-Z0 on it so that I have more room for my vm's but
no redundancy so i just have to backup vm's often *
