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 * On Tue, Feb 7, 2023 at 4:22 PM Michael Butash via PLUG-discuss < plug-discuss@lists.phxlinux.org> wrote: > That sounds like what they call "fakeraid" using the rst controller, > really there is no need to anymore.
