I want to combine those 4 1 TB SSDs into a 4 TB volume and move my home directory onto that volume. Would OpenZFS be a suitable reliable solution? Has anyone on this forum done something similar?
From my experience, you'll probably wish you hadn't done it. I would use it for storage but not as a home/boot disk. There are too many issues with bottlenecking, the performance won't be good enough even with SSDs. One moment you will have good speeds and then for no obvious reason it will slow down to almost nothing or start spiking. You will probably encounter finder pauses. Use it as a "working drive" but not as a home/boot drive. Either way, please share your results!!
