I feel like hardware raid is relic from the pre multi core CPU days, given that was less than 20 years ago it makes me feel old

Can confirm that moving a zfs array to a new system after a failure is simply connect the disks and zpool import -f <pool_name>

Every raid card I use now is put in hba mode it’s just simpler to deal with

I can recommend the nanopi r4s, supported by openwrt, ipfire and I think opnsense. Ive been using it as my main router for almost a year now on a symmetric 1Gb connection. Best part is it’s super cheap and tiny
