In case anybody&#x27;s still reading this, I have a couple of use-case questions.<p>I&#x27;m planning on setting up my first volume pool using 4 5TB Seagate ECs. I can&#x27;t get any more than four to begin with.<p>I was intending on using mirrored vdevs, as I&#x27;d heard that was basically the easiest way to get started. This is entirely for personal use, and I don&#x27;t need &quot;enterprise&quot; read&#x2F;write rates (the hardware I&#x27;ll be starting with certainly won&#x27;t manage that), and it won&#x27;t be the end of the world for (very very rare) resilvers to take all night.<p>Are there any advantages to <i>not</i> using mirroring, ie using one of the RAIDZ variants? I&#x27;ve already accepted the idea of having to buy new disks two at a time so I can spin up a new vdev with them.
