transitioning away from raid but I do love zfs for flexibility. A lot of the data I have is important for someone or somebody, so zfs and a decent backup solution is in use just to make sure. I went bananas and picked up a used Supermicro 4-node server that takes dual E5 Zeons (V1 or V2) with 2xE5-2620s and 49 gig ram in each node for £80 (I’m in the UK). Plenty of power and next is to upgrade the cpus to slightly better cpus to reduce power as it currently uses 2 nodes and I am pulling around 300 watts most of the time. Backup solution is an old Ryzen 3200G with 32 gig ram that runs truenas and has 5x3tb spinny drives in it
