Here&rsquo;s what I learned about ZFS pool design, hardware selection, and avoiding common pitfalls.</p> <h2 id="hardware-selection">Hardware selection</h2> <p>Budget was a constraint, so I optimized for reliability over raw speed:</p> <ul> <li><strong>Motherboard</strong>: ASRock B550M with ECC support</li> <li><strong>CPU</strong>: Ryzen 5 5600G (low TDP, enough for transcoding)</li> <li><strong>RAM</strong>: 32GB ECC DDR4 (ZFS loves RAM for ARC cache)</li> <li><strong>Boot</strong>: 2x 120GB SSD in mirror (TrueNAS boot pool)</li> <li><strong>Data</strong>: 4x 8TB Seagate Exos in RAIDZ2</li> </ul> <h2 id="why-raidz2">Why RAIDZ2</h2> <p>With 4 drives, RAIDZ2 gives you two-drive redundancy at the cost of usable space. The math:</p>
