Not catastrophically — a single ext4 volume quietly developing bad sectors while I assumed everything was fine, because nothing was loudly failing. By the time I noticed, the damage was done. That experience sent me down a rabbit hole that ended at <strong>ZFS</strong>, and I haven&rsquo;t looked at another filesystem for storage since.</p> <h2 id="why-zfs">Why ZFS?</h2> <p>Most filesystems trust that the data written to disk is the data you&rsquo;ll read back. ZFS doesn&rsquo;t. It checksums every block, every read, and every write. Silent data corruption — the kind that accumulates invisibly over years — is caught and, with redundancy, corrected automatically. For a home lab storing years of photos, documents, and media, this matters.</p>
