+    "bodyRich": "For TrueNAS, allocate at least <strong>8 GB RAM</strong> for basic operation and more for demanding workloads. ZFS uses RAM for its ARC cache, but there is no universal 8 GB performance cliff for every ZFS-based NAS. Check the chosen distribution’s requirements and size memory for its disks, services and apps; lighter OMV or Rockstor setups can need less."
