If I had 4 devices (2x SSD and 2x NVMe) I'd love to test how striped-LVM-on-pair-of-RAID-1s compares against RAID-1+0, but unfortunately I'm unlikely to be able to justify buying that hardware at once just for testing purposes. To be honest if I'm happy with the NVMe then I'll probably just switch to NVMe in future as it's actually cheaper (but has only 3 vs 5 year warranty, and a quarter the write endurance). Cheers, Andy
