Helediron<p>I am replacing old hard disks in my backup server. The task will take about two weeks! Not because of much work, but disk wipes. Old 7x8TB take about two days to pre-read, wipe, and post-read . New 5x24TB disks take probably three times longer I presume.</p><p>The old disks are now about ten years old. They were recycled about four years ago from main server to backup. One of them has reported few bad blocks. I'll recycle them to cold backups by splitting each to two 50%/50% partitions, and then a mirrored ZFS pool on top. Assuming they last another five years, that's total 15 years life cycle. <br><a href="https://techhub.social/tags/homelab" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>homelab</span></a> <a href="https://techhub.social/tags/unraid" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>unraid</span></a> <a href="https://techhub.social/tags/ZFS" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ZFS</span></a> <a href="https://techhub.social/tags/backup" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>backup</span></a> <a href="https://techhub.social/tags/recycling" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>recycling</span></a></p>
